CUbIQ Technologies Unveils Quantum Key Distribution Breakthrough
THIS IS A PRESS STATEMENT FROM CUBIQ TECHNOLOGIES
Eindhoven, Netherlands - September 29, 2025 - CUbIQ Technologies, a Dutch pioneer in quantum communication, today announced a successful proof-of-concept (POC) showcasing a disruptive quantum key distribution (QKD), the first scalable QKD over DWDM solution in partnership with Coherent Corp. and Liberty Global. The demonstration marks a major milestone in the evolution of scalable, energy-efficient quantum-secure communications.
The POC, set to be showcased at ECOC 2025 (September 29 - October 1), features CUbIQ’s Continuous Variable Quantum Key Distribution (CV-QKD) transceiver in a QSFP-28 pluggable form factor - an industry-first innovation that integrates seamlessly into existing fiber infrastructure. This compact module enables quantum-safe encryption directly within the PTX Series routing platform, leveraging Coherent’s high-performance 400G ZR QSFP-DD DCO pluggable optical transceivers.
“CUbIQ’s mission is to make quantum security practical, scalable, and accessible. This collaboration proves that quantum-safe networking enabled by QKD can be achieved in an industry standard QSFP-28 form factor pluggable without overhauling existing infrastructure - ushering in a new era of secure communications.”
Coherent, an industry leader in high-speed optical transceiver technology, is partnering with CUbIQ to pioneer the next generation of secure, high-capacity optical pluggable transceivers, leveraging their proven expertise in advanced optical design and volume manufacturing.
“Coherent is excited to join Liberty Global, and CUbIQ in advancing quantum-safe networking. This proof-of-concept highlights how our optical technologies can enable secure, high-performance communications in the post-quantum future.”
Liberty Global, a global leader in converged broadband and mobile services, selected CUbIQ’s pluggable QKD solution to future-proof its network against quantum-enabled threats. The company views quantum technology as a strategic priority and sees this innovation as a potential game-changer for secure data transmission across its extensive European footprint.
“Liberty Global is thrilled about QKD pluggable technology, as it allows us to enhance our security portfolio with best-in-class, scalable, and cost-effective network encryption transport services.”
The joint solution enables Liberty Global and other customers to reinforce their IPsec and MACsec infrastructure with quantum-safe encryption—protecting networks, services, and end-user data from emerging quantum threats.
