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.

Quantum Technologies (QT) are at a pivotal moment with major global efforts underway to translate quantum information science into new products that promise disruptive impact across a wide variety of sectors from communications, imaging, sensing, metrology, simulation, to computation and security. Our world-leading Centre for Doctoral Training in Quantum Engineering will evolve to be a vital component of a thriving quantum UK ecosystem, training not just highly-skilled employees, but the CEOs and CTOs of the future QT companies that will define the field. Due to the excellence of its basic science, and through investment by the national QT programme, the UK has positioned itself at the forefront of global developments. There have been very recent major [billion-dollar] investments world-wide, notably in the US, China and Europe, both from government and leading technology companies. There has also been an explosion in the number of start-up companies in the area, both in the UK and internationally. Thus, competition in this field has increased dramatically. PhD trained experts are being recruited aggressively, by both large and small firms, signalling a rapidly growing need. The supply of globally competitive talent is perhaps the biggest challenge for the UK in maintaining its leading position in QT. The new CDT will address this challenge by providing a vital source of highly-trained scientists, engineers and innovators, thus making it possible to anchor an outstanding QT sector here, and therefore ensure that UK QT delivers long-term economic and societal benefits. Recognizing the nature of the skills need is vital: QT opportunities will be at the doctoral or postdoctoral level, largely in start-ups or small interdisciplinary teams in larger organizations. With our partners we have identified the key skills our graduates need, in addition to core technical skills: interdisciplinary teamwork, leadership in large and small groups, collaborative research, an entrepreneurial mind-set, agility of thought across diverse disciplines, and management of complex projects, including systems engineering. These factors show that a new type of graduate training is needed, far from the standard PhD model. A cohort-based approach is essential. In addition to lectures, there will be seminars, labs, research and peer-to-peer learning. There will be interdisciplinary and grand challenge team projects, co-created and co-delivered with industry partners, developing a variety of important team skills. Innovation, leadership and entrepreneurship activities will be embedded from day one. At all times, our programme will maximize the benefits of a cohort-based approach. In the past two years particularly, the QT landscape has transformed, and our proposed programme, with inputs from our partners, has been designed to reflect this. Our training and research programme has evolved and broadened from our highly successful current CDT to include the challenging interplay of noisy quantum hardware and new quantum software, applied to all three QT priorities: communications; computing & simulation; and sensing, imaging & metrology. Our programme will be founded on Bristol's outstanding activity in quantum information, computation and photonics, together with world-class expertise in science and engineering in areas surrounding this core. In addition, our programme will benefit from close links to Bristol's unique local innovation environment including the visionary Quantum Technology Enterprise Centre, a fellowship programme and Skills Hub run in partnership with Cranfield University's Bettany Centre in the School of Management, as well as internationally recognised incubators/accelerators SetSquared, EngineShed, UnitDX and the recently announced £43m Quantum Technology Innovation Centre. This will all be linked within Bristol's planned £300m Temple Quarter Enterprise Campus, placing the CDT at the centre of a thriving quantum ecosystem.
