Oxford Quantum Circuits (OQC) is a private quantum computing company founded in 2017 by CSO Dr. Peter Leek. The company says it builds “Application Optimised Compute” and provides quantum-compute-as-a-service. Its technology is explicitly described as based on superconducting circuits, with a patented Coaxmon architecture and proprietary dual-rail Dimon qubit technology.
According to its company materials, OQC has delivered three generations of quantum systems: Sophia, Lucy, and Toshiko. The company states that its systems are available through the cloud, can be colocated in enterprise and sovereign data centres, and can be embedded through APIs. OQC also says its current-generation devices are deployed in London and Tokyo, and that its next-generation system, OQC GENESIS, is intended for installation in New York City. The homepage also states that OQC raised $350 million in a Series C round.
