Quantum computers will transform numerous industrial sectors, from the major aerodynamic simulations used to optimise jet engine design, through artificial intelligence, machine learning and the data economy, to drug discovery. Quantum computers are set to be as game-changing as the development of conventional computers in the last century, as they will be able to solve high-impact problems which would take the fastest supercomputer billions of years. A primary goal of UK's National Quantum Technology Programme is translating the UK's academic excellence in developing practical quantum computers into economic prosperity, by building a quantum computing industry sector including relevant supply chains. The biggest remaining challenges in realising universal quantum computation are in scaling up to fault-tolerant machines with millions of qubits. The quantum hardware developed in QCorrect will be capable of overcoming the limitations faced by competitors around the world propelling the UK to become a leader in commercial quantum computing. While competing platforms based on superconducting qubits are limited in the number of qubits they can realise because of the requirement to cool microchips to -273C, our platform is based on trapped-ions and does not require such cooling. Our platform is also suitable for implementation of efficient and scalable error-correction algorithms which improve the performance of the computer whilst reducing the hardware requirements. The combination of these factors offers the opportunity to develop systems featuring much larger qubit numbers. Full silicon microchip integration will allow the creation of self-sufficient electronic quantum computing modules to be deployed and made cloud-accessible for end-user investigation during the project. Hardware/software co-development is led by system integrator Universal Quantum and quantum software developer Riverlane, together with leading subsystem manufacturers for vacuum systems (Edwards) and microwave technologies (TMD Technologies, Diamond Microwave) incubating a quantum computing supply chain in the UK. The University of Sussex will perform use-case demonstrations and deliver performance enhancements aided by theoretical innovations from Imperial College London. In order to ensure a pathway to commercialisation, applied Computational Fluid Dynamics (CFD) experts at Rolls-Royce and STFC will work with Riverlane and UQ to develop a quantum approach to solving partial differential equations that underpin commercially-relevant simulations in the UK aerospace sector. Exploitation/dissemination partners Sia Partners will develop a roadmap to commercialisation of application-specific tools in CFD and Qureca will develop broader use-cases that depend on solving partial differential equations. The consortium will execute the first use-case demonstrations and streamline hardware/software development towards practical applications.

Modern life is unthinkable without computers. An ever-increasing amount of energy is required for computing, impacting the global drive to a low-carbon economy, and Moore's law is slowing as the circuit dimensions approach physical limits. Quantum computers can create a computational space much larger than their classical counterparts. They will shape computing, science and commercial standards by solving numerical problems that are currently out of reach in fields including chemistry, material science, logistics, artificial intelligence, machine learning and cryptography. The race is on to build the world's first practical quantum computers, which requires scaling from arrays of a few dozen qubits, to thousands, to millions of qubits. To achieve this, we need to create integrated systems of qubit arrays and control electronics. In most implementations, the qubits require cryogenic cooling, typically to a fraction of a degree above absolute zero. Yet conventional CMOS electronics is designed to operate at room temperature, and if these chips are cooled to cryogenic temperatures, the operating characteristics of the transistors change markedly, and they no longer work as intended. This problem is well recognised in the industry. Major players such as Google, Microsoft and Intel have all invested in progressing towards building specialised "cryo-CMOS" control electronics that can operate in the very cold environment that the qubits require. Most quantum computing companies, however, don't have the resources to develop silicon CMOS processes for cryogenic temperatures. Instead, they rely on semiconductor fabrication via foundries (e.g., TSMC, Globalfoundries), looking to various silicon IP companies to provide technology to enable them to exploit the foundries' manufacturing capability. This model has worked well for development of chips for room temperature operation, however it requires significant updating to create new designs that can work at ultra-cold temperatures. This project brings together world-leading expertise in CMOS design and quantum computing. We will create updated process design kits (PDKs) for cryogenic temperatures and an ecosystem of silicon IP products to enable chip designers to exploit foundries using the established fabless model. Thus the project will enable quantum computing companies to scale their hardware systems to create a new generation of more powerful quantum computers.

Without an operating system, computers would be much less useful. Before the invention of operating systems, computers could only run one calculation at a time. All tasks had to be scheduled by hand. Operating systems automate the scheduling of tasks and make sure that resources such as memory and disk space are allocated properly. Because operating systems simplify computers, everyone can handle them and benefit from them. Quantum computers are a new type of powerful computer. Big and high-quality quantum computers can outperform conventional computers at specific tasks, such as predicting the properties of a drug. Currently, it is difficult for users to interact with quantum computers because there is no good operating system. The systems that exist don't schedule tasks optimally and cannot perform calculations quickly. Building this operating system is difficult -- many have tried and no solutions have worked. We have invented an operating system to overcome this technical challenge: NISQ.OS. While competitors present quantum computers as a "black box", NISQ.OS exposes all its different elements. Many of them look far more familiar than you might think. Quantum computers consist of a quantum processing unit, which contains the qubits, a couple of layers of special-purpose chips that control the qubits, and a conventional computer for overall control. By providing access to all these layers of the "quantum computing stack", we give the user the power to schedule tasks in an optimal way. This will improve the performance of quantum computers by a 1,000-fold compared to other leading approaches. Once we integrate hardware and software tightly, we expect that the performance will improve by 1,000,000-fold. We have assembled a group of experts from across the UK to build the operating system. This includes the UK's leading quantum hardware companies, Hitachi, Oxford Quantum Circuits, SeeQC, Duality Quantum Photonics, Oxford Ionics, and Universal Quantum; Riverlane, a quantum software company; Arm, a UK-based chip manufacturer; and the National Physical Laboratory. The National Physical Laboratory plays an important role because their expertise lies in developing technical standards for breakthrough technology. To build our operating system, we need to define a new standard interface between software and hardware that everyone can use. Our project will attract many important customers, such as pharmaceutical or chemical companies, as well as the financial industry. Because our operating system is so much better, they will want to run their applications on UK-based quantum computers.
