Quantum Bridge Technologies, a cybersecurity company developing quantum-safe cryptographic infrastructure, has raised US$8 million in Series A funding led by Primo Capital SGR. The round also included Wayra (Telefónica), Cadenza VC, Club degli Investitori angels, HPE, and Bacchus Venture Capital.
The new funding brings Quantum Bridge’s total capital raised to US$16 million and will support global expansion as enterprises and governments accelerate quantum-safe migration strategies.
Protecting Critical Infrastructure From Quantum Threats
Quantum Bridge develops security technology designed to protect communications and sensitive data against future quantum computing risks. The company’s patented Distributed Symmetric Key Establishment (DSKE) protocol enables decentralized key generation and management, reducing single points of failure while improving scalability and resilience.
The platform is designed to integrate into existing infrastructure and security environments without disrupting current operations, helping organizations strengthen protection across networks, optical encryptors and application-level systems.
Focus on Defence, Telecom and Financial Services
The company is targeting sectors facing growing cybersecurity pressure, including financial services, telecommunications, government and defence.
“National security can’t wait for perfect conditions,” said Mattia Montagna, co-founder and CEO of Quantum Bridge Technologies. “We build quantum-safe systems that work inside real networks today — systems designed to keep protecting sovereign communications as the threat landscape evolves. This funding means we can meet more organizations where they are, and get them protected faster.”
Scaling Quantum-Safe Infrastructure
The new investment will support product scale-up and broader deployment of quantum-safe cybersecurity infrastructure globally as organizations prepare for long-term cryptographic risks linked to quantum computing.
