About Quantum Bridge Technologies
Canadian cybersecurity company developing quantum-safe cryptography and secure communications technology.
Operating context
Quantum Bridge provides crypto-agile key distribution through its Symmetric-Key Distribution System and Distributed Symmetric Key Establishment protocol. In a Toshiba collaboration, DSKE linked Toronto and Cambridge quantum-key networks over conventional international communications, with draft ETSI interoperability interfaces. JETRO also reports an April 2026 Japanese proof of concept that maintained encrypted communications using DSKE as a backup to Toshiba QKD. These demonstrations clarify both an international interconnect role and a resilience use case, without implying direct transatlantic transmission of quantum states.
