The Micius satellite’s QKD system, designed for secure communication, faces vulnerabilities due to laser timing flaws. A 300 ps delay allows eavesdroppers to distinguish signal and decoy states, nullifying security. Enhanced testing and synchronization are critical for future systems.
Heriot-Watt University has unveiled HOGS, a £2.5 million Optical Ground Station that secures satellite links using quantum key distribution. The facility also monitors space debris and integrates with a live fibre network for rapid prototyping. UK companies can now test next-generation optical communications without hefty infrastructure costs.
Quantropi teams with HIMERA to equip G1 PRO tactical radios with quantum-level encryption, protecting military communications from next-gen threats.
Quantinuum, Mitsui, and NEC successfully transmitted quantum tokens over a 10km fibre network. This trial demonstrates unforgeable financial instruments with rapid settlement. Quantum technology is reshaping the security landscape in finance.
Telia has conducted Finland’s first test of quantum encryption technology within a commercial network, advancing national efforts to secure critical infrastructure. The test, part of the NaQCI.fi project, showcases the potential of Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) in safeguarding sensitive communications.
Latvia is embarking on a groundbreaking project to establish a national quantum communications infrastructure system and network. The project involves collaboration between the Latvia State Radio and Television Centre, Tet, the Electronic Communications Office of Latvia, and the Institute of Mathematics and Computer Science of the University of Latvia.
Researchers from universities and institutes around [Ireland] will pool their expertise to examine how infrastructure and the transmission of data in Ireland can be secured using quantum technology.
EAGLE-1 satellite for ESA’s end-to-end Quantum Key Distribution system to launch on the Vega-C rocket from Europe’s Spaceport in French Guiana in 2024. The satellite will be placed into Low Earth Orbit (LEO).
Rivada Space Networks (RSN) is partnering with SpeQtral to demonstrate the technical compatibility of adding a QKD encryption layer to enhance the security of communications over low earth orbit satellite constellations.
Although the word “qudit” might look like a typo, this lesser-known cousin of the qubit, or quantum bit, can carry more information and is more resistant to noise — both of which are key qualities needed to improve the performance of quantum networks, quantum key distribution systems and, eventually, the quantum internet.
