OQC’s quantum computer is already a complete functioning unit, including the backend, the control, the hardware and the software. With four-qubit, our device is the most advanced and the only commercially available quantum computer in the UK.
Superconducting circuits are highly engineerable compared with other approaches and give our engineers the power to design our systems with a high degree of customisation.
With this approach we are able to work on the principles of standard circuit design, working on silicon chips (with a thin metal layer on top). This means that our materials are also easy to source and our components are easier to make.
The key challenge of superconducting circuits for quantum computation, is the ability to scale qubit numbers whilst maintaining qubit quality and control in order to reach a commercially useful level of processing power. ‘Traditional’ 2D circuits require increasingly intricate engineering to route control wiring across the chip to the qubit. This both degrades the quality of the qubits and increases the chance of costly engineering errors.
Our core innovative technology – the Coaxmon, solves these challenges: it has a three-dimensional architecture that brings key componentry off-chip for vastly increased simplicity, flexibility, engineerability and – crucially – scalability.
In other words, the essence of our innovation is the ability to scale our key technologies without any compromise on quality. It is unique in the world of quantum computers.
The Coaxmon was developed by OQC’s Founder Peter Leek, at the University of Oxford. It is patent protected, exclusively in-licensed to OQC from the University of Oxford, and filed in Europe (EPO), the US, Japan and China.
OQC’s Lab, where qubits are developed, measured and operated, is a state-of-the-art facility, with cryogenic tools that can create temperatures much colder than space, and bespoke control hardware generating low-latency qubit pulses.
Currently hosted by the University of Oxford, our lab will soon be brought in-house to allow us to accelerate R&D. This is also a very important milestone in making our technology commercially available by enabling us to extend access to our quantum computer to more partners and customers.
Thanks to our work with our partners, and access to a world-class facility, the SuperFab at Royal Holloway, University of London, OQC has developed the first commercial qubits in the UK.
