The UK’s most advanced
quantum computer

OQC designs unique superconducting circuits,
the most promising approach in the industry.

OQC’s patented Coaxmon

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. 

In this extract of “Quantum Supremacy & AI, with Stephen Fry”, a visual explanation is given of how our solution brings 3D to quantum tech thanks to our innovation, the Coaxmon.

A state-of-the-art lab

OQC’s Lab, where qubits are developed, measured and operated, is a state-of-the-art facility, with cryogenic equipment that can create temperatures much colder than space, and bespoke control hardware generating low-latency qubit pulses.

OQC’s lab is fitted with an ISO7 cleanroom with a ducted fume cupboard, a controlled area for several cryostat rigs, including power and data supplies with control units and cooling pumps. A bespoke compressor plant solution was designed with chilled water distribution systems to service cryostats and to keep the quantum computers functioning without fail.
