National Quantum Strategy roadmap: Quantum computing

 

Introduction

Advances in quantum science have the potential to transform how people work and live. Investments over many decades have made Canada a global leader in quantum technologies and research, with a growing ecosystem of world-class centres of quantum expertise in universities and businesses across the country. As the rest of the world expands their own quantum strategies and initiatives, Canada must continue to invest wisely, innovate and commercialize to stay ahead while ensuring it is positioned as an integral contributor to the global supply chain.

To strengthen Canada's quantum ecosystem, the Government of Canada launched the National Quantum Strategy (NQS) in January 2023, and allocated $360 million in dedicated funding, in addition to leveraging a number of broad-based large-scale programs. The NQS aims to: amplify Canada's strength in quantum research; grow quantum technologies, companies and talent; and solidify Canada's global leadership in quantum science and its commercialization. The NQS sets out three key missions on: quantum computing and software; communication and post-quantum cryptography; and sensors. To pursue these missions, NQS activities are supporting the three pillars of research, talent and commercialization. Success requires collective effort by many actors, including governments (federal, provincial, territorial and Indigenous governments and organizations), academia and industry, as well as non-profits such as incubators, accelerators and industry associations.

Text description
  • NQS launched January 2023
  • NQS road mapping 2023-24
  • Programming adjusted/new activities
  • Potential new investments 2025 and beyond

Road-mapping exercises engaged stakeholders to help identify challenges, gaps, opportunities, milestones and actions required to achieve success in each of the NQS missions. Provinces actively involved in the development of quantum hubs were engaged and their input has been incorporated. However, other provinces and territories may also be undertaking actions to support quantum science and technology. Informed by these roadmaps, the Government is working with partners to advance the missions and may explore additional investments.

This roadmap charts a course forward for the quantum computing hardware, software, algorithms and applications mission. It will be updated periodically to reflect advances in quantum technologies that could drastically change timelines or lead to new applications.

Overview of quantum computing hardware and software

Quantum computers (hardware) harness the principles of quantum mechanics such as superposition, interference and entanglement to perform calculations. While classical computers store and process information in binary bits (i.e., 0 or 1), quantum computers do this by exploiting the superposition principle and use quantum bits (or qubits), where 0 and 1 are encoded simultaneously into quantum systems, such as atoms, spins and superconducting systems. This property can allow quantum computers to solve complex problems beyond the ability of classical computers, with potential applications in machine learning; advanced materials, process, molecule and drug simulations; as well as optimization and logistics.

At present, there are many quantum computing platforms including superconducting, photonic, silicon spin, neutral atoms or ion trap-based technologies.Footnote 1 There are also different quantum computing systems such as quantum annealers and gate-based systems.Footnote 2 Quantum software and algorithms enable the operation and design of quantum computers, and the development of applications. These quantum hardware systems often interact with classical computers, with growing opportunities for quantum-classical hybrid applications.

Forecasts anticipate that quantum computing hardware and software will account for up to US$68 billion globally by 2030.Footnote 3 Canada is well-placed to be a key player due to trusted world-class expertise across the country, comprising a growing ecosystem of universities, industry pioneers along with start-ups, service providers and larger domestic and multi-national firms including regional quantum hubs in Alberta, British Columbia, Ontario and Quebec.

Canadian researchers and companies are at the forefront of the international race to build a scalable, high-performance, fault tolerant quantum computer. Canadian firms have developed quantum computing systems and algorithms with the potential for solving challenges that are too complex, costly or time-consuming to solve with conventional technologies.

Developing a strong Canadian quantum software and service industry is critical as well. Canadians are also leaders in developing software to control quantum computers and link them to classical computer systems and creating applications that make these systems useful. This advantage could benefit Canadians by transforming a number of sectors, such as making supply chains more efficient, modelling climate change, developing new materials and drugs, and more. Early-stage quantum applications are already being implemented, supporting industry awareness and demonstrating potential applications that will drive industrial progress and further promote the quantum sector.

Quantum computing hardware and software mission

Make Canada a world leader in the continued development, deployment and use of quantum computing hardware and software—to the benefit of Canadian industry, governments and citizens.

This mission's long-term goal is to build and scale a fault tolerant quantum computer. Although quantum computers are currently available, their error rates are high and qubit counts are low, making their utility limited to solving specific, pre-defined problems. Several research and development challenges need to be addressed to achieve this goal.

Support in the near term will focus on research needed to develop and test the next breakthroughs in hardware and other elements of the full computing stack; transitioning R&D into commercial settings through developing use cases and applications; as well as growing the quantum workforce.

To develop components of a quantum computer and secure the supply chain, the following priorities have been identified:

  • develop quantum computing hardware, including hybrid parallel processing systems, simulation and modelling of quantum hardware
  • develop new quantum algorithms and advance quantum computing software
  • identify and alleviate supply chain and infrastructure challenges and develop domestic manufacturing capacity
  • provide access to multiple quantum computing platforms including annealing and gate-model quantum computing systems and various qubit modalities

To increase adoption of quantum computing technologies by receptor sectors, the following priorities need to be advanced:

  • develop proofs of values and use cases, linking producers with end-users to support adoption
  • consider ways of offsetting research and development and integration costs and accelerate testing and development of commercial applications
  • develop quantum resource estimations, benchmarks and standards

To support the quantum computing ecosystem in general, it is crucial to focus on these priorities:

  • strengthen the talent pipeline
  • promote Canadian quantum computing science, technology and industry domestically and internationally
  • address barriers to growth for Canadian quantum computing and software companies
  • identify societal impacts and develop an ethics framework
  • protect intellectual property (IP) and improve the security posture of Canadian researchers and innovators

Programming supporting the quantum computing mission

There are several programs and initiatives across the Government of Canada that are already supporting the quantum computing mission:

Furthermore, the Department of National Defence and Canadian Armed Forces released its Quantum Science and Technology Strategy Implementation Plan, Quantum 2030, in 2023. It identifies four promising quantum technologies with defence and security applications and lays out a seven-year plan to develop prototypes, including in quantum computing (quantum algorithms for defense and security) ready to be tested in the field by 2030.

CIFAR supports academic research, training, and knowledge mobilization, through its Quantum Information Science and Quantum Materials programs, and CIFAR Azrieli Global Scholars program. CIFAR-supported researchers have contributed to fundamental research and technological advances in a range of topics, from superconductivity and graphene-based two-dimensional materials, to distributed quantum networks and quantum error correction. There have been 19 Global Scholars affiliated with CIFAR's two quantum research programs since 2016.

Fundamental research that aims to advance our understanding of the science underlying future breakthroughs is important for success and is supported through existing mechanisms such as NSERC Discovery Grants.

Applied research that aligns with the three NQS missions is funded through specific calls under NSERC Alliance and ISC. Business and non-profit support will continue to be provided through the Industrial Research Assistance Program (IRAP), Strategic Innovation Fund, Regional Development Agency programming, Global Innovation Clusters, Strategic Science Fund, Innovation for Defence Excellence and Security, Deep Tech Venture Fund, etc.

1. Developing components of a quantum computer and securing the supply chain

There are many quantum computing platforms under development, each advancing at a different speed and technology readiness level. Annex A includes a summary of platforms and their advantages and disadvantages. Given the current level of development, it is not yet clear which platforms will produce a fault tolerant quantum computer. As such, Government programs will be inclusive of different hardware and software approaches.

While impressive progress has been made in the development of quantum computing modalities, advances are still needed to achieve fault tolerant quantum computing. Gate model quantum hardware and software development must advance further to become capable of solving problems that are useful to end-users. Research is needed to identify the threshold for when classical approaches to optimization becomes intractable and to what extent quantum gate and annealing systems will deliver broad commercial advantage.

Qubit performance: Several aspects of qubit performance will need to advance to enable the scale up of quantum computing including:

  • develop a scalable qubit and control architecture that includes error correction
  • demonstrate logical qubit performance in a scalable architecture
  • demonstrate interacting logical qubits
  • develop general purpose quantum processing units (QPU) capable of running a well-defined target application

Quantum processor modelling: Modelling the performance of quantum processors, including noise, heat dissipation and other challenges can improve the design of processors, error correction codes and scaled-up systems, and predict processing capabilities. Before fault-tolerant quantum computers are available, modelling will help us understand the types of problems that these systems can best address and test how different hardware approaches would perform without investing in prototype systems. In addition, device simulation software may help training the workforce at institutions where access to quantum computing hardware is limited.

Quantum simulation: Outside of gate-based quantum computing, there is vast potential for simulating problems using quantum systems. Initiatives that could help support adoption include developing programmable quantum simulators for computationally intensive problems beyond the reach of classical computers.

Hybrid computing capacity: Exploiting the full benefits of quantum computing will require interconnected systems of quantum and classical computers, to make use of what each type of system does best and to make it easy for users to access quantum computers in a trusted and private way. This parallel processing will require research and development of novel algorithms or techniques to pass information between the classical and quantum processors, or interconnects and hardware.

Distributed quantum computing: With limited processor sizes, the ability to distribute entanglement between processors and perform "multicore" operations across a network would expand the effective size of the processor. This requires the development of quantum computers that can interface with networking channels. Distributed quantum computing and blind quantum computing, which would allow for use of quantum computers on untrusted sites, are further explored in the quantum communications roadmap.

a. Key challenges

Quantum computing is a complex area of active research that requires advances in multiple open problems to become successful. This section outlines some of the key challenges, although given the emerging nature of the field, it is not possible to provide a complete list.

Access to foundries and other manufacturing limitations

There is limited domestic industry supporting the quantum computing supply chain, e.g., superconducting chip fabrication, dilution refrigeration manufacturers for at-scale systems, etc. There is also a need for domestic integration of high-performance computing and quantum data centres that are inclusive of different computing technologies.

Several approaches to quantum computing (superconducting, photonics, spins, quantum dots, etc.) rely upon modifications to the existing technology used for manufacturing silicon-based integrated circuits. To scale-up beyond university lab experiments, access to commercial grade foundries is required.

One barrier is the lack of Canadian semiconductor manufacturing firms and infrastructure. Smaller companies and researchers rely on foundry services to complete their prototypes with processes that can be scaled up to mass manufacturing. In Canada, there are few facilities that can fabricate quantum components at scale. Currently, commercial prototype designs must be sent out of Canada to be fabricated. and some Government programs are restricted from funding these activities. Furthermore, a robust process to reliably produce quantum chips at scalable levels, similar to mature technologies like Complementary Metal-Oxide-Semiconductors (CMOS), is not yet available.

Capturing more of the supply chain for development activities inside Canada can increase supply chain resiliency and security, generate economic growth, and foster innovation and collaboration. Discussions between the government and the quantum community can help determine the necessity and feasibility of a domestic footprint for quantum computer components. In cases where key components are only available internationally, establishing agreements to secure Canadian access may be necessary. Enhancing our understanding of the global supply chain and determining Canada's role within it will be necessary.

Software and algorithms

The development of quantum software faces additional hurdles, such as super-polynomial speed-up for simulating error correction codes. Quantum computer codes should have encoding and decoding efficiencies to enable quantum error correction and distributed quantum computing, reduce overhead, and avoid lag in the communication between quantum and classical devices.

Algorithms that use noisy quantum computers are in high demand because they can lower the physical and engineering requirements for building useful quantum machines. Recent demonstrations of high-fidelity computations on present-day hardware with over one hundred physical qubits suggest that useful quantum computing applications are possible in the near-term with error mitigation schemes instead of requiring full error correction.Footnote 4,Footnote 5,Footnote 6,Footnote 7 Such algorithms can provide applications and benchmarks for current quantum computers, and insight into the potential of quantum computing systems, which can incentivize larger scale adoption. Development of algorithms and software for use cases on near-term systems will ensure that businesses and researchers are ready to quickly realize the full advantages of fault-tolerant hardware once it is available. The development of quantum simulators capable of optimizing the generation, fusion, and measurement protocols in noisy environments is also required.

Given that the commercialization of annealing and gate-based systems is anticipated to speed up as hybrid quantum-classical algorithms expand, research and development of innovative hybridization techniques is also required. Ultimately, advancing quantum software is critical in developing applications that drive adoption, thus increasing demand for hardware and the rest of the quantum computing supply chain.

Establishing a cost-effective supply chain for critical materials and components

Developing a quantum computer may require materials or components that may either be unavailable or prohibitively expensive. In many cases, these materials and components are not currently produced in Canada or not at sufficient levels to meet demand.

Cooling some types of quantum hardware requires helium-3, an isotope that has an unmatched level of efficiency in carrying away the heat. However, helium-3 is extremely rare and the main supply comes from aging nuclear warheads and heavy water reactors. In less than two decades the global demand for and price of helium-3 has substantially increased. Furthermore, the distribution of helium-3 is highly regulated and is subject to strict government controls due to security concerns.

Similarly, the high-purity (chemical and isotopic) silicon wafers needed for some architectures are becoming increasingly restricted and expensive. Neon gas is a critical component in semiconductor production that is also becoming inaccessible.Footnote 8 Expanding access to alternative sources of purified silicon and neon gas is critical to scaling these technologies.

Simulation of qubit noise and quantum error correction to help scale architectures

Today's gate-model hundred-qubit quantum computers require a dramatic scale up to potentially millions of qubits to solve certain problems. Although a variety of qubit technologies have been demonstrated, scalability remains a major hurdle. Modelling the noise sources and thermal budget limits of qubits through analytic approaches and technology computer-aided design software will enable the limitations to be better understood and help advance manufacturing capabilities including scale up of quantum computers. Developing and commercializing hardware modeling and design solutions would also enable Canadian companies to become a critical part of the global quantum-hardware supply chain.

Additionally, it will be important to lower error rates so that adding qubits and longer coherence requirements does not undermine system performance or require substantial resources for error correction.

Quantum error correction schemes will also need to be refined in parallel with hardware development to scale quantum computing systems. Quantum error mitigation and suppression methods, which generally use a combination of classical and quantum computations, have demonstrated benefits that could allow quantum computational advantage before full error corrections schemes are usable. While these methods have been implemented in commercial systems, further improvements are needed. Error correction and suppression strategies will also need to be tailored to different qubit platforms.

Quantum annealing systems will need to continue to scale the number of devices and produce architectures with increased connectivity and enhancements in device coherence.

Packaging

Widespread adoption of quantum computers will require addressing all parts of the systems, especially the packaging challenge of larger and more complex Quantum Processing Units (QPUs), ensuring that quantum systems or sub-systems can be purchased and used reliably. Developing systems that are standardised, interoperable and robust will help transition the technology from complex lab setups to modular and robust devices. This could involve miniaturisation and streamlining control electronics, automation and environmental shielding.

b. Action plan

2. Increasing adoption of quantum computing technologies by receptor sectors

For widespread adoption to occur, end-users will need evidence that quantum computers can meet their needs in a manner that is superior to existing classical technologies (i.e., computational, cost and/or energy advantage). The development of use cases and proofs of value will help demonstrate added value and justify adoption, thus increasing demand.

The full range of potential applications to real-world problems remains uncharted. Quantum computers are good tools for solving problems that have special properties or structure. However, identifying these structures requires a complex theoretic effort, which uses basic research in quantum algorithms and their capabilities as well as a knowledge of the computational challenges faced by industry. To date, there are only a few algorithms with practical utility. Identifying additional use cases for fault-tolerant quantum computers, annealers and quantum hybrid technologies can help drive the invention of the required algorithms.

Training within firms is also crucial for the diffusion of this technology and widespread adoption.

Furthermore, establishing workflows and data processing pipelines is still needed for scientific and business applications. Quantum resource estimation must be undertaken to determine the hardware requirements.

Other impediments to adoption in receptor industries include:

  • low awareness of how quantum technologies can affect them, compounded by lack of in-house quantum talent and quantum literacy
  • challenges with interoperability with existing systems and high costs to incorporate quantum technologies into business processes
  • lack of awareness of the management of innovation required to adopt disruptive technology
  • lack of standardization and regulatory uncertainty on quantum technologies
  • risk aversion and resistance to change

Initiatives that help de-risk adoption of quantum technologies by end-users, support Canadian participation in standards setting activities, bolster the talent pipeline, and raise awareness of quantum applications can help address these issues.

3. Supporting the quantum computing ecosystem

Several initiatives can be undertaken to support the quantum computing ecosystem as a whole. These initiatives will also address issues identified in the other priorities.

Attraction, development and retention of a quantum workforce

A diverse, skilled and large quantum workforce will be needed to support the activities described in this roadmap. This includes highly qualified personnel with scientific skills to develop advances in fundamental quantum science, technical skills to develop quantum technologies, and entrepreneurial skills to bring research from the lab to the market. Quantum-literate employees, entrepreneurs and researchers, along with technicians trained in the installation, integration, operation, repair and maintenance of quantum technologies and associated components such as dilution refrigerators are also needed.

Partnerships and coordination between academia and industry on training will help ensure that future talent needs are met. This could include providing access to quantum technologies for students, identifying industry training needs, jointly developing curriculum and creating co-op/internship opportunities.

It will be critical for Canada to invest in developing and retaining quantum expertise, as well as accessing global pools of talent. Being internationally competitive on student, postdoctoral and industry compensation and the work environment will be key. In addition, there is a need to increase the number of graduates with quantum-related skills. Efforts must also continue in addressing the underrepresentation of equity-seeking groups in scientific, technology, engineering and mathematics disciplines (STEM).

Talent for quantum R&D also comes from a global marketplace. Bringing talent to Canada and retaining it can be challenging. Visa timing and costs can increase the complexity of this process. Canada must make it as easy and quick as possible to bring and keep those with quantum expertise.

In December 2022, the National Quantum Strategy Secretariat held two virtual workshops led by Immigration, Refugee and Citizenship Canada, which provided an overview of immigration programming and a Q&A session. More work will be needed to address this issue.

Ethical and social considerations

The broad usage of quantum computers may impact many sectors of the economy. It will be necessary to identify social implications and ethical considerations. This could include:

  • export of technologies that could have dual uses in the civilian and military sectors
  • equity, diversity and inclusion considerations in the quantum workforce and among those who would benefit from the technology
  • environmental impact of quantum technologies
  • potential of quantum computers to break widely used encryption methods with impacts on privacy and security

In addition, quantum machine learning may result in faster data analysis, processing of larger datasets, and useful generalizations from a smaller amount of training data than is possible with classical machine learning. This could enable improved identification and surveillance, resulting in privacy impacts.

Quantum machine learning and artificial intelligence (AI) may also exacerbate discrimination against marginalized groups when trained on bad data and biased algorithms and used in automated decision-making systems (e.g., hiring, medical diagnosis, etc.).Footnote 29

In view of these observations, learning from ethical issues and regulations in AI and other emerging technology areas and applying them to quantum technologies is key. This will help mitigate unintended consequences in the development of regulations. Further research on the social impacts of quantum technologies and development of an ethics framework will ensure these technologies benefit society and negative impacts are mitigated.

Programming and funding

As an emerging technology, quantum computers have different commercialization pathways than other technologies, thus requiring different supports. Quantum computing start-ups may require many years or decades of investments before they can bring a product to market. Unfortunately, the duration of funding support offered by several federal innovation programs is much shorter than the time needed to develop quantum computers. In other cases, program requirements (such as number of employees, years since incorporation, or revenue thresholds) makes it challenging to support early-stage entrepreneurs. As well, many programs are tailored towards providing loans rather than grants, which is challenging for startups. Consideration of longer funding duration, follow-up investments, cash advances, and more flexible program requirements would better support the development of quantum technologies.

Access to funding through other Canadian sources, such as venture capital, angel investors, business incubators and other forms of private equity, are critical to building a vibrant quantum ecosystem and are the largest source of funding for quantum companies. Without sufficient funding from start-up to scale-up, there is a risk that Canadian quantum companies will be acquired by foreign companies, leading to a loss of intellectual property (IP), talent and returns to other countries.

Intellectual property

Encouraging Canadian quantum innovators to protect and hold the rights to their intellectual property assets will stimulate growth, encourage innovation, attract investment and protect their businesses. Innovators will need to develop a global IP protection strategy.

The Canadian Intellectual Property Office (CIPO), a special operating agency of ISED, provides online learning tools and resources and delivers IP services in Canada. Its IP advisors help small-and-medium sized businesses understand the value of their IP and develop an IP strategy. Information about applying for IP rights, enforcement and commercialization, as well as relevant government programs, is also available through the IP Village. Financing and tailored advisory services are available through the NRC IRAP's IP Assist program, BDC Capital's IP-Backed Financing and ISED's ElevateIP by way of several business accelerators and incubators targeting startups.

Research security

Safeguarding Canada's quantum research and its resulting assets from foreign theft, interference or misuse, is essential for maintaining the country's economic stability, national security, and technological advancements. Quantum research and its underlying data and resulting technologies are defined as 'sensitive research', and could be used to advance a foreign state's military, intelligence or surveillance capabilities. Sensitive research includes 'dual-use research', which refers to products, data, knowledge or technologies that have both purely scientific and military or intelligence applications. From a research security perspective, Canadian researchers may be developing or collecting knowledge or information for legitimate scientific purposes, but that information could be illicitly acquired or exploited by others with the intent to cause harm to Canada's national interests. Unauthorized access to quantum research and technology can undermine Canada's national security interests or those of its allies, including the disruption of the economy or critical infrastructure.

The Government of Canada remains committed to protecting quantum research and technologies against foreign interference, espionage and theft. Research security is a collective effort – researchers, academia, firms, funding organizations and governments have a shared responsibility to identify and mitigate any potential national security risks related to research. In consultation with the science and research community, the Government of Canada has taken several measures to protect the country's world-class research and continues to provide support and guidance for implementing research security due diligence. This includes a series of federal policies, including the new Policy on Sensitive Technology Research and Affiliations of Concern, and the National Security Guidelines for Research Partnerships. Other advances that support the implementation of Canada's research security policies include the establishment of a Research Security Centre, as well as $50 million in funding through the Research Support Fund for eligible post-secondary institutions to build their research security capacity. In addition, the Government of Canada continues to release and develop new tools and resources that are available through the Safeguarding Your Research portal.

Canada is focused on ensuring that Canada's research ecosystem remains as open and internationally collaborative as possible, in alignment with its foundational principles of transparency, merit, academic freedom and reciprocity. In so doing, this enhanced security posture is meant to safeguard, but not limit, Canada's cutting-edge research by mitigating research security risks.

Security related to quantum communication and cryptography is addressed in the quantum communication and post-quantum cryptography roadmap.

International partnerships and agreements

No country can succeed on its own. Developing partnerships with like-minded countries will improve Canadian research and commercial outcomes. Promoting the Canadian quantum sector abroad and developing partnerships can help attract talent, secure access to global supply chains, further R&D, increase exports and advance adoption of quantum technologies. Efforts to date have included issuing joint co-operation statements with the UK and Japan, and negotiation of others is underway. As well, international missions with key markets will help Canadian companies to access new markets.

Annex A: Current status of quantum computing technologiesFootnote 30

Technology Basic description Advantages Disadvantages/ challenges
Ion trap Individual ions held in a vacuum via an electromagnetic trap generated by surrounding electrodes. Laser pulses perform gate operations. Long coherence times; mature technology. Fluctuating electric and magnetic fields push on the ions, causing decoherence. Slow gate times. Development of scalable architectures based on integrated traps.
Neutral atoms and molecules Individual atoms or molecules trapped in arrays of optical tweezers. Gates are implemented with lasers pulses. Long coherence times; scalable; tunable interactions; readily integrated into optical networks. Relatively new technology (but rapidly developing within a mature field); gate fidelities need to be improved; requires good laser stabilization; relatively slow gate times.
Photons Information encoded in polarization, orbital angular momentum, number (0/1 photons), time, or frequency modes. Information encoding and gate operations through phase shifters, beam splitters, optical media, interferometers, frequency filters. Detection through avalanche photodiode detectors (APDs), superconducting nanowire single-photon detectors (SNSNDs), single-photon avalanche detectors (SPADs). Lack of interaction with environment reduces decoherence; mobility makes them ideal for quantum network communication; built on silicon infrastructure; robust over long-distance transmission; easy access to qudits and high information encoding; operable at room temperature. Difficult to make photons interact with each other, which affects the implementation of quantum gates; difficult to make them interact with each other; Kerr media is absorptive and scatters light; requires precise control of large circuits of linear optical components.
Emitter-photon hybrid (indirect photonic interactions) While quantum information is encoded and carried in photons, the state preparation and multi-qubit interactions e.g., two-qubit gates on photons, are realized indirectly through intermediate quantum emitters. E.g., quantum dots, and defects in nanodiamonds. Once a highly entangled photonic state is attained, the information processing is done through measurement-based or fusion-based quantum computing protocols, which are implemented on cluster states (state of the art with qubits, in principle extendible to qudits). On-demand generation and distribution of entanglement through the use of intermediate matter qubits, thereby eliminating the necessity of photon-photon interactions through nonlinear media. Generating cluster states of dimension >1 generally requires using either coupled emitters, which is technologically challenging, or using fusion gates, which is probabilistic in nature. Difficult to achieve photon indistinguishability using different emitters.
Photonically-linked spins Electron and nuclear spins of defect centres in silicon or other semiconductors. Linked by optical photons and spin-photon interface. Photons allow long-range interaction; spins have low decoherence and high-fidelity operations; built on silicon infrastructure. Slower operations for nuclear spins; probabilistic entanglement layer.
Measurement-based / Fusion-based photonics quantum computing Hybrid quantum computing such as measurement-based quantum computing. For instance, quantum dots can be used to generate photonics cluster and graph states, which could then be fused together to generate larger photonics graph state and to perform large-scale quantum computing. A hybrid approach tries to get the best of both worlds by using interactions in quantum dots for photon generation and low decoherence of photons due to lack of interactions with environment. A hybrid approach requires high fidelity and high efficiency emission of photons and high collection efficiency. It requires indistinguishability of photons for effective fusion.
Quantum dot Semiconductor particles a few nanometers in size down to single atom quantum dots. Can be constructed in semiconductors with controllable numbers of electrons, including 0 to 1. The spin of these electrons can be used as qubits. Potential scalability with well established fabrication techniques; all electrical operation, including electrically controllable spin-spin coupling; potential high density with single atom quantum dots. Decoherence due to electrostatic fluctuation; requires cryogenic conditions and additional development of atomically precise manufacturing (APM) infrastructure.
Solid-state spin Nuclear or electron spin of donor atoms in a semiconductor or NV centers in diamond. Highly coherent; potential CMOS compatibility APM gives a path towards deterministic positioning of single atom quantum memories and precision fabrication of colour centers in diamond and silicon. High precision fabrication requirements; slower operations for nuclear spins.
Superconductors Charge, current, or energy of superconducting circuit. High compatibility with existing fabrication technique; electronic control; easy coupling; mature technology used in fault tolerant approaches. High quality materials and nanofabrication required for high-performance devices, large physical footprint and colder temperatures required. Appropriate facilities for install/operation also required.
Bosonic codes in superconductors Qubits encoded in the energy states of cavities using superconducting quantum chips. Small or no overhead required for quantum error correction; fast computational clock speed; leverage highly performant and scalable hardware platform. Very low error rates and fault tolerant gates possible but not yet demonstrated; access to state-of-the-art superconducting quantum chips.
Topological Non-abelian anyons can be created in superconductors and topological insulators. Gates performed by braiding the anyons or by performing measurements. Hardware level resistance to error. Synthetic photonic lattices explorable for large topological structures. Less mature than other approaches; hard to engineer.
