Company description

Oxford Quantum Circuits develops quantum computers using superconducting circuits, which uses a specific element that is not used in regular circuits.

The company was founded by Dr Peter Leek, who is based at the Clarendon Laboratory, Department of Physics, University of Oxford, and is aiming to build a quantum computer based upon a superconducting circuit approach to forming qubits. The intention is to leverage the latest technology in this field and overcome the key challenge that has confounded researchers to-date: scaling the system up to a large number of qubits.

DECIDE: Dimon Error Correction Integrated into a Data-centre Environment.

1 Apr 2025 to 31 Mar 2026

Awarded
£2,337,475
Total cost £3,895,792

The UK Government has set its ambitious target to national industry and academia of achieving 1 million quantum operations (the MegaQuop) by 2028 and 1 trillion quantum operations (TeraQuop) by 2035 through its Quantum Mission. The key challenge today to reach this computational advantage is how we build Quantum Computers (QCs) capable of large numbers of...

A novel, quantum model for NLP: a step towards AGI.

1 Sep 2023 to 28 Feb 2025

Awarded
£34,672
Total cost £49,532

Large language models such as ChatGPT have recently undergone a step-change in their user-perceived efficacy, and as such they have caught the attention of journalists and then the imagination of the general public. These A.I. systems appear to deliver responses to user-posed questions that are both informative and delivered with substantial expertise. Th...

Reliable, high throughput production and characterisation of coherent superconducting devices

1 Sep 2020 to 31 Aug 2023

Awarded
£1,072,575
Total cost £1,532,250

Advanced production capabilities have allowed conventional electronics based on semiconductors to become more powerful and support almost all technologies we use today, from laptops to washing machines and cutting edge medical equipment. But semiconductors are now facing hard limits as the miniaturisation of components reaches closer to the atomic scale. ...

NISQ.OS

1 Aug 2020 to 31 Jul 2023

Awarded
£703,424
Total cost £1,004,891

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 syste...

Compilation & Circuit Layout Optimisation For Superconducting Quantum Processor

1 Mar 2018 to 28 Feb 2019

Awarded
£99,924
Total cost £142,749

Oxford Quantum Circuits Limited (OQC), established in June 2017, are developing quantum computing processors based on superconducting circuits. A fundamental business question for OQC is what applications (quantum algorithms) are best suited for its technology, and how to most efficiently realise first generation processors that will be capable of running...
