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.

Toshiba Digital Solutions Corporation (Toshiba Digital Solutions), the Toshiba Group company driving forward industry-leading solutions in digital and quantum technology, in partnership with KT Corporation (KT), a leading telecommunications service provider and its collaborator in quantum secure communication in South Korea, has demonstrated how banks and financial networks can be protected from cyberattacks by quantum computers by bringing hybrid quantum secure communications, comprising quantum key distribution (QKD) and post-quantum cryptography (PQC), to secure communications at Shinhan Bank, one of South Korea’s leading banks.

Q*Bird, Single Quantum and Eurofiber have been awarded a €1 million subsidy to push the boundaries of Quantum Key Distribution (QKD) technology, further securing digital communications. Announced at the 2025 Mobile World Congress in Barcelona.

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.

In a pioneering field test, quantum entanglement was successfully distributed among three devices located in different buildings on the TU Delft Campus. Utilizing self-developed optical devices, TNO established connections over 150 meters of free space and 200 meters of optical fiber. This small-scale configuration simulates a future satellite-ground network connection. The communication system’s components were developed by six different companies.

TU Wien, the University of Innsbruck and the company qtlabs are working together on a major FFG-funded project to make quantum cryptography secure and suitable for practical use.

Quantum key distribution (QKD) is a method for two parties, Alice and Bob, to generate a shared secret key that is secure against eavesdropping, based on the principles of quantum physics. Recent research at ICFO has focused on continuous variable QKD (CV-QKD), which uses readily available optical components and existing telecom infrastructure.

ID Quantique (IDQ), a global leader in Quantum-Safe solutions and Quantum Communications, today announced that its high-performance Clavis XG series, has become the first product of its class globally to receive an official national security approval from South Korea’s National Intelligence Service (NIS).

Interference (excess noise) to quantum signals from sunlight has slowed down the creation of a global scale quantum communications network – but now physicists at Heriot-Watt University have proposed a way to tackle this ‘daylight noise’ issue, paving the way for all-day satellite transmission.
