Over the next few decades, quantum computing (QC) will transform the way we design new materials, plan complex logistics and solve a wide range of problems that conventional computers cannot address. The Hub for Quantum Computing via Integrated and Interconnected Implementations (QCI3) brings together >50 investigators across 20 universities to address key challenges, and deliver applications across diverse areas of engineering and science. We will work with 27 industrial partners, the National Quantum Computing Centre, the National Physical Laboratory, academia, regulators, Government and the wider community to achieve our goals. The Hub will focus on where collaborative academic research can make transformative progress across three interconnected themes: (T1) developing integrated quantum computers, (T2) connecting quantum computers, and (T3) developing applications for them. Objectives for each are outlined below. (T1) Developing integrated quantum computing systems, with a goal of creating quantum processors that will show real utility for specific problem examples. Objectives: OB1.1: Demonstrate quantum advantage in analogue platforms with neutral atoms and photons OB1.2: Make neutral atom quantum simulation platforms available in the cloud OB1.3: Develop new applications for these and other near-term systems (T2) A key challenge of building the million qubit machines of the future is that of 'wiring' together the quantum processors that will create such a machine. The Hub will develop technologies that help achieve this and develop models to understand how such machines will scale. Objectives : OB2.1: Develop interconnect technologies for quantum processors OB2.2: Demonstrate blind computing and multi-component networks with trapped ion quantum computers OB2.3: Demonstrate transduction and networking of superconducting processors (T3) Developing applications in science and engineering, including materials design, chemistry and fluid dynamics. Objectives: OB3.1: Develop new methods for materials and chemical system modelling and design, fluid dynamics, and quantum machine learning OB3.2: Identify the nearest routes to quantum advantage for these application areas OB3.3: Develop implementations of these algorithms on T1 and T2 Hardware These will be supported by work in overarching tools (T4) that can be used across the themes of the Hub, including error correction, digital twins, verification and software stack optimisation. Skills and training Hub partners will work with end-users, our students and researchers, and partners across the UK National Quantum Technologies Programme (UKNQTP) to ensure members of the Hub have the skills they need. Specific objectives include: Provide training in innovation, commercialisation and IP, Equality, Diversity and Inclusion and Responsible Research and Innovation (RRI) to Hub partners Provide reports and training to end-users, working in partnership with the NQCC and others Continue to provide advocacy and advice to policy makers, through work in such areas as RRI Exploitation and Engagement: The Hub will build on the strong engagement activities of the UK programme, further developing the technology pipeline. We will play a key role in strengthening and expanding the UK ecosystem through events, networking and education. Specific goals are to: Broaden the partnership of the Hub, bringing new academic, government and industrial partners into the Hub network Contribute to regulation and governance through programmes of work in standards and RRI, and close collaboration with UKNQTP partners Support the generation and protection of intellectual property within the Hub, and its exploitation Develop Hub and cross-Hub outreach initiatives, working with the RRI team, to help ensure the potential of quantum computing for societal benefit can be realised

The EPSRC Quantum Computing and Simulation Hub will enable the UK to be internationally leading in Quantum Computing and Simulation. It will drive progress toward practical quantum computers and usher in the era where they will have revolutionary impact on real-world challenges in a range of multidisciplinary themes including discovery of novel drugs and new materials, through to quantum-enhanced machine learning, information security and even carbon reduction through optimised resource usage. The Hub will bring together leading quantum research teams across 17 universities, into a collaboration with more than 25 national and international commercial, governmental and academic entities. It will address critical research challenges, and work with partners to accelerate the development of quantum computing in the UK. It will foster a generation of UK-based scientists and engineers equipped with the new skill sets needed to make the UK into a global centre for innovation as the quantum sector emerges. The Hub will engage with government and citizens so that there is a wide appreciation of the potential of this transformative technology, and a broad understanding of the issues in its adoption. Hub research will focus on the hardware and software that will be needed for future quantum computers and simulators. In hardware we will advance a range of different platforms, encompassing simulation, near term quantum computers, and longer term fully scalable machines. In software the Hub will develop fundamental techniques, algorithms, new applications and means to verify the correct operation of any future machine. Hardware and software research will be closely integrated in order to provide a full-stack capability for future machines, enabled by the broad expertise of our partners. We will also study the architecture of these machines, and develop emulation techniques to accelerate their development. Success will require close engagement with a wide range of commercial and government organisations. Our initial partners include finance (OSI), suppliers (Gooch & Housego, Oxford Instruments, E6), integrators and developers (OQC, QM, CQC, QxBranch, D-Wave), users from industry (Rolls-Royce, Johnson Matthey, GSK, BT, BP, TrakM8, Airbus, QinetiQ) and government (DSTL, NCSC), and other research institutions (NPL, ATI, Heilbronn, Fraunhofer). We will build on this strong network using Industry Days, Hackathons and targeted workshops, authoritative reports, and collaborative projects funded through the Hub and partners. Communications and engagement with the community through a range of outreach events across the partnership will inform wider society of the potential for quantum computing, and we will interact with policy makers within government to ensure that the potential benefits to the UK can be realised. The Hub will train researchers and PhD students in a wide range of skills, including entrepreneurship, intellectual property and commercialisation. This will help deliver the skilled workforce that will be required for the emerging quantum economy. We will work with our partners to deliver specific training for industry, targeting technical, commercial and executive audiences, to ensure the results of the Hub and their commercial and scientific opportunities are understood. The Hub will deliver demonstrations, new algorithms and techniques, spinout technologies, and contribute to a skilled workforce. It will also engage with potential users, the forthcoming National Centre for Quantum Computing, the global QC community, policy makers and the wider public to ensure the UK is a leader in this transformative new capability.
