- In April 2025, KETS Quantum Security, a Bristol-based startup, delivered a prototype quantum cybersecurity system to BT for testing. This silicon chip-based technology uses light to transmit quantum-encrypted keys, enabling secure communications and detection of any interception attempts.
- In March 2025, Cloudflare announced the integration of post-quantum cryptography into its Zero Trust Network Access solution. This enhancement aims to secure data as organizations route communications from web browsers to corporate applications, with plans to extend support to all IP protocols by mid-2025.
- In December 2023, Bengaluru-based QNu Labs secured $6.5 million in a Pre-Series A1 funding round. The investment supports the development of their quantum technology solutions, including quantum key distribution and quantum random number generators.
- In November 2022, QuintessenceLabs launched its qOptica QKD technology, which provides enhanced security against cyber-attacks. It uses continuous-variable quantum key distribution (CV-QKD) to distribute keys securely over an optical link.
- In March 2024, China Telecom Quantum Information Technology Group Co. acquired a 23.1% stake in QuantumCTek for $265 million. This strategic move aims to bolster China Telecom's presence in the quantum communication sector.
