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.

Next-generation communications security tech company Q*Bird has made a significant step forward in quantum networking, with the creation of technology to allow multiple users to set up a quantum link simultaneously.

ESA, together with a Starion-led industrial consortium, has marked a significant milestone in quantum communications technology with the successful implementation of a terrestrial quantum key distribution (QKD) link. The link took place between its European Space Security and Education Centre (ESEC) in Belgium and a data centre in Luxembourg. The development comes as part of the International Use Cases for Operational QKD Applications and Services (INT-UQKD) project, which exemplifies ESA's commitment to bridging the gap between advanced space technology and practical business applications.

TIM Group’s companies Sparkle, the first international service provider in Italy and among the top global operators, and Telsy, center of excellence for communication security and cybersecurity with its participated company QTI Quantum Telecommunications Italy, leading Italian QKD provider, announce the successful completion of a Proof of Concept (PoC) on a high-capacity link between two data centers in Athens, secured with Quantum Key Distribution (QKD).

A research team from the University of Science and Technology of China (USTC), in collaboration with several research institutions in China and South Africa, has developed the world’s first quantum microsatellite and demonstrated real-time quantum key distribution (QKD) between the satellite and multiple compact, mobile ground stations.

Telefónica, in collaboration with Vithas and technology providers LuxQuanta and QoolNet, has successfully established a quantum-secured fiber-optic link between two hospitals in Madrid. This project demonstrates the feasibility of Quantum-Safe communication for healthcare institutions, ensuring the long-term protection of sensitive medical data against emerging threats from quantum computing.

Telefónica, in collaboration with Vithas and technology providers such as LuxQuanta and QoolNet, has managed to communicate two hospitals within the Community of Madrid by protecting them through a quantum fiber optic link. With this project, the operator demonstrates the viability of Quantum-Safe securitization of communications between healthcare centers, so that in the future it will be possible to guarantee the immunity of sensitive data such as healthcare data against possible attacks from quantum computers.

In a rapidly evolving cyber threat landscape, ensuring secure communication is more critical than ever. Synergy Quantum, a pioneer in integrating Post-Quantum Cryptography (PQC) with Quantum Key Distribution (QKD), is at the forefront of advancing the future of cybersecurity. With its groundbreaking Satellite-Based Quantum Key Distribution (QKD) technology, Synergy Quantum is setting new standards for ultra-secure encryption across the globe, combining quantum technologies to safeguard sensitive data against emerging threats.

The trial, presented live at the European Quantum Technology Conference, demonstrates the ability to provide connectivity services protected with QKD on an existing combined fibre optic network.

Q*Bird is excited to share their recent achievement in securing quantum communications. Q*Bird, in collaboration with SURF and Quantum Delta NL, has successfully installed a multi-user, multipoint-to-multipoint Quantum Key Distribution (QKD) network in Utrecht. This achievement sets a new benchmark for secure communications, addressing the critical need for advanced data protection in the research and education sector.
