Quantum Bridge Technologies has closed a $8 million Series A funding round led by Primo Capital SGR to accelerate the global transition to quantum-safe cybersecurity infrastructure.
Founded in 2019 by Mattia Montagna and Hoi-Kwong Lo, Quantum Bridge emerged from one of the world’s leading quantum security research groups to deliver quantum-safe security solutions.
Quantum Bridge addresses the systemic threat posed by quantum computing to current cryptographic infrastructure. The company’s patented Distributed Symmetric Key Establishment (DSKE) protocol enables organisations to generate, distribute, and manage symmetric keys through a decentralised architecture, removing single points of failure, improving scalability, and strengthening long-term cryptographic resilience.
Quantum Bridge brings advanced cryptographic security into practical deployment, grounded in well-established principles that have stood the test of time. Designed to work across existing infrastructure, vendors, and security layers, the company’s platform allows organisations to add quantum-safe protection from optical encryptors to application-level systems without disrupting existing operations.
By making defence-grade security practical for commercial environments, Quantum Bridge helps customers advance their quantum-safe migration with greater scalability, flexibility, and confidence.
