Oxford Quantum Circuits is a quantum processor manufacturer using superconducting technology and formed in 2017 and based in the UK. The $100 million Series B investment was led by SBI Investment with additional participation from previous investors Oxford Science Enterprises (OSE), University of Tokyo Edge Capital Partners (UTEC), Lansdowne Partners, and OTIF, acted by manager Oxford Investment Consultants (OIC). It is the largest Series B investment so far achieved in the UK for a quantum company. Previously, they had raised  £41 million ($51.8M USD) in 2022 in a Series A funding which was also the largest Series A funding for a quantum company in the UK.

The company has also announced that the Toshiko processor is now available in private beta. It is an upgradable design that currently supports 32 qubits. It is intended for deployment at commercial data centers where it can be integrated with the classical HPC resources for a hybrid compute environment. The company has adopted a Digital Fabric Interconnect, to enable secure, hybrid compute for customers. This type of installation is attractive to customers concerned about security who would rather not send their data to external cloud providers. The processor can be programmed with QIR (Quantum Intermediate Representation), OpenPulse and OpenQASM programming languages.

Additional details about the Toshiko release and the Series B investment are available in a press release available here. Additional information about the Toshiko processor can be found on a web page here and a technical product sheet here.
