CUbIQ Technologies Leads Quantum Key Distribution Breakthrough at ECOC 2025
CUbIQ Technologies, alongside Coherent Corp., HPE Networking, and Liberty Global, have successfully demonstrated a groundbreaking Quantum Key Distribution (QKD) proof-of-concept (PoC) at the European Conference on Optical Communication (ECOC) 2025 in Copenhagen. The PoC incorporates QKD technology directly into a compact transceiver, marking a significant step towards quantum-safe encryption.
Until now, QKD required large, dedicated 19-inch hardware, making it impractical for widespread use. CUbIQ's innovation lies in developing a Continuous-Variable QKD (CV-QKD) transceiver in a compact QSFP28 form factor, small enough to fit into HPE's Juniper switches and routers. This breakthrough enables a simplified, integrated approach to QKD, making it more accessible and feasible for real-world applications.
The PoC aims to enable quantum-secure MACsec encryption based on QKD key exchange. This is crucial as quantum computers threaten classic encryption methods like RSA or ECC. Quantum-safe solutions like QKD are becoming increasingly important to secure our future digital infrastructure.
The successful demonstration of this compact CV-QKD transceiver paves the way for wider adoption of QKD in network security. By enabling quantum-secure MACsec encryption, it addresses the looming threat of quantum computers to traditional encryption methods. CUbIQ Technologies, along with its partners, has brought us a significant step closer to a quantum-safe future.
