Toshiba Quantum Technology Division

Toshiba Quantum Technology Division is based in Cambridge, United Kingdom, headed by Andrew Shields, operating as part of Toshiba Europe Limited's Cambridge Research Laboratory. Toshiba started quantum cryptography research in 1999 and manufactures the Multiplexed QKD System at their Cambridge UK base. In March 2025, Toshiba Europe Limited launched a commercial QKD system integrating post-quantum cryptography (PQC) using NIST's ML-KEM standard, offering enhanced quantum-safe security. In May 2024, Toshiba developed a QRNG fully integrated into semiconductor chips ready for mass manufacture. The division demonstrated record-breaking QKD transmission distances and pioneered quantum-secured network deployments across Europe and Asia. Toshiba collaborates with telecommunications operators including BT Group and global financial institutions to deploy quantum-safe communications infrastructure. The company serves telecommunications operators, government agencies, financial institutions, and critical infrastructure sectors requiring commercial-grade quantum key distribution systems and quantum-safe networking equipment.
