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.

Thales Alenia Space, the joint venture between Thales (67%) and Leonardo (33%), and Hispasat, Redeia’s satellite services operator, have announced the start of the development, manufacturing, verification, and validation phase of the QKD-GEO prototype, Spain’s quantum key distribution system from geostationary orbit. With a budget of 103.5 million euros, the QKD-GEO mission is a project initiated by the Spanish Secretary of State for Telecommunications and Digital Infrastructures and funded by European funds from the Recovery, Transformation, and Resilience Plan (PERTE Aeroespacial), for which contracting is managed by CDTI.

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).

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.

The Monetary Authority of Singapore (MAS), DBS, HSBC, OCBC, UOB, SPTel and SpeQtral today signed a Memorandum of Understanding (MoU) to embark on quantum security collaboration and study the application of Quantum Key Distribution (QKD) [1] in financial services. QKD can help financial institutions (FIs) protect the exchange of cryptographic keys to address the cybersecurity threats posed by quantum computing.

BeQCI, the consortium charged with deploying the first ever open quantum communication infrastructure in Belgium, has reached an important milestone in its Quantum Key Distribution (QKD) mission. Belnet, the Belgian National Research Network, has successfully set up the required infrastructure and realized the first QKD links together with imec and UGent.

SpeQtral, SafeQuantum, Antaris and QTD Systems announce the establishment of a satellite Quantum Key Distribution (QKD) receiver node at the historic carrier hotel data center building, 60 Hudson Street in New York City. This strategic initiative aims to enable the secure establishment of quantum keys between Singapore, the United States and Europe, enabling quantum-safe communications that will safeguard global financial transactions.
