Quantum Bridge Technologies

Quantum Bridge Technologies develops quantum-safe cybersecurity solutions that protect critical infrastructure and sensitive data from both current and future quantum computing threats. The company's flagship product, the Symmetric-Key Distribution System (SDS), is a crypto-agile security solution that combines Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD), and its patented Distributed Symmetric Key Establishment (DSKE) protocol to deliver high-entropy cryptographic keys across network environments. The platform is layer- and vendor-agnostic, seamlessly scalable to entire networks of any size, and designed for crypto-agility to meet evolving security needs. Quantum Bridge differentiates itself through its information-theoretically secure approach based on decades of research, interoperability with top network appliance providers, and partnerships with organizations including Toshiba Europe (demonstrating global quantum-safe networking) and Italtel (protecting critical communications for the post-quantum era). The company serves organizations requiring future-proof protection of critical data and communications infrastructure. Founded in 2019 and headquartered in Toronto, Canada, Quantum Bridge Technologies has raised $8 million in a Series A round backed by the Canadian Space Agency, Juniper Networks, Primo Capital, Wayra, Cadenza, Club degli Investitori, Hewlett Packard Enterprise, and Bacchus Venture Capital.
