According to Korean media reports, KT successfully implemented wireless quantum encryption over 1-kilometer and 2-kilometer distances in 2022 and 2023 respectively using its independently developed wireless quantum key distribution technology, and is currently pursuing the development of 10-kilometer transmission technology, the longest distance in Korea yet.

The ParisRegion Quantum Communication Infrastructure (QCI) consortium, led by Orange has successfully implemented its first quantum communication network in existing fibre optic infrastructure. The ParisRegionQCI project, a consortium of industrialists, university researchers and start-ups set out to demonstrate the feasibility of quantum key distribution (QKD) based on existing terrestrial fibre networks.

Researchers at the Institute for Quantum Computing (IQC) in Canada have developed a quantum source intended for inclusion in the Quantum Encryption and Science Satellite (QEYSSat) project. QEYSSat will test a communication method known as quantum key distribution and schedule to launch the quantum source next year. It will carry this small quantum source into space to transmit photons with polarization-encoded between the satellite and ground stations on Earth.

SpeQtral, SafeQuantum, Antaris, and QTD Systems jointly announced yesterday that they will collaborate to establish a satellite Quantum Key Distribution (QKD) receiver node in New York City, aiming to enable quantum-safe communications between Singapore, the United States, and Europe. It is reported that SpeQtral will provide satellite QKD technology and quantum optical ground stations, SafeQuantum will be responsible for deploying the optical ground station in QTD Systems data centers and connecting them to the existing Quantum Secure fiber networks.

Korean Telecom (KT) announced yesterday that it has completed preparations for commercializing post-quantum cryptography (PQC) technology. KT independently developed a prototype of the quantum encryption communication device "QENC" and designed PQC solution services through technology transfer. KT's PQC solution utilizes encryption keys generated by quantum key distribution devices and keys generated by PQC algorithms. It applies the CRYSTALS-Dilithium and CRYSTALS-Kyber algorithms, which will soon be standardized by NIST, to enhance data security.

Toshiba reached a strategic cooperation agreement with the Canadian nonprofit organization Numana in Quebec yesterday to enhance the Kirq quantum communication testbed in the Province of Quebec. The Kirq testbed has been launched in Sherbrooke, and two additional hubs will be launched in Montreal this summer and in Quebec City by early 2025. It is understood that these testbeds will be built using Toshiba's state-of-the-art quantum key distribution (QKD) equipment.

Quantum communications technology company SpeQtral and Toshiba Asia Pacific Pte. Ltd. (TAPL), announced yesterday that they will present their latest quantum key distribution (QKD) products and services during the Asia Tech Singapore (ATxSG) 2024 event. This Singaporean subsidiary of Toshiba is supporting the strategic partnership between Toshiba Digital Solutions Corporation and SpeQtral by providing cutting-edge quantum-safe data communication technologies to Singaporean enterprises,  fortifying their digital infrastructure against emerging cybersecurity threats.
