The Integrated Quantum Networks Hub will address the challenges underpinning the establishment of a “quantum internet”, by developing the novel technologies, protocols and industry standards necessary for the deployment of a secure, scalable, quantum communications infrastructure for the UK and beyond.

KDDI Research, Inc. (“KDDI Research”), and Toshiba Digital Solutions Corporation (“Toshiba Digital Solutions”) have developed a multiplexing technology for quantum key distribution (QKD) that is theoretically impossible to eavesdrop. This technology assigns secret keys to the C-band and high-volume data signals to the O-band, enabling multiplexed transmission over a single optical fiber. Furthermore, utilizing this technology, we have successfully transmitted secret keys and high-capacity data signals at 33.4 Tbps over 80 km for the first time.

Toshiba Europe Limited has today announced that its commercially available quantum key distribution (QKD) systems now natively incorporate the latest post quantum cryptography (PQC) standard, bringing an additional layer of security to its quantum-safe networking platform.

Toshiba Corporation, a leading innovator in technologies realizing quantum key distribution (QKD) for secure network communications, has announced two significant advances in essential technologies for establishing global-scale quantum networks: Large-Scale Quantum Key Distribution Network Control Technology, and High-Speed Quantum Key Distribution Technology.

A research team from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), led by Prof. PAN Jianwei, ZHANG Qiang, and CHEN Kai, in collaboration with CHEN Jingling from Nankai University, has achieved the loophole-free test of Hardy's paradox for the first time.

This constitutes a major milestone on the path to the certification of QKD products. The Protection Profile was developed within the framework of the ETSI Industry Specification Group ISG-QKD, to which ID Quantique has contributed since its inception in 2008. The Protection Profile has subsequently been fully validated by the SGS evaluation lab in Graz, and the evaluation has been certified by the German certification body BSI.

Researchers at Deutsche Telekom Innovation Laboratories (T-Labs), together with the quantum networking company Qunnect (US & NL), have reached a milestone on the path to the quantum internet: demonstration of sustained, high fidelity (99%) transmission of entangled photons across 30 kilometers of commercially deployed fiber for 17 days.

The UN has declared 2025 as the “International Year of Quantum Science and Technology. EPFL is leading the way in cutting-edge quantum research and the democratization of these exciting technologies.

Adtran today announced that Colt Technology Services has successfully completed a quantum-secured encryption trial across its metro and long-haul optical wave networks using Adtran FSP 3000 technology. The trial assessed the performance of both post-quantum cryptography (PQC) and quantum key distribution (QKD) to safeguard critical data from emerging cybersecurity threats. By successfully securing traffic between Colt’s London and Frankfurt sites as well as across three locations in London, the trial demonstrates the viability of quantum-secured encryption solutions in a multi-vendor, disaggregated environment. Colt aims to develop customizable solutions based on the findings, helping businesses prepare for quantum-era security challenges.
