DAS Photonics' Faint Pulse Source Passes Space Qualification for ESA's QKDSat, Europe's Satellite Key Distribution Mission
The European Space Agency confirms that DAS Photonics completed the ECSS qualification campaign of the Quantum Faint Pulse Source for QKDSat and delivered the engineering model to Redwire Europe. We read what a qualified engineering model means for satellite quantum key distribution, why the trusted-node architecture belongs in every procurement conversation, and where the mission sits beside SAGA and EuroQCI in Europe's secure connectivity build-out.
QuINSiDa Lab Demonstration Targets Free-Space QKD, LiFi and Encryption for Harbors, Ships and Fiberless Sites
A six-partner German consortium demonstrates free-space quantum key distribution at two wavelengths running beside LiFi data transport, key management and encryption in one working wireless stack. We read what line-of-sight quantum-secure communications would let a harbor, a ship or a forward site protect, and measure the laboratory result against the BSI position paper, the missing key-rate figures and the field trials that still separate this bench from a pier.
A Quantum Key Crosses From Fiber to Open Air Without a Trusted Node
A Tel Aviv University team, with the Hebrew University and HEQA Security, demonstrated end-to-end quantum key distribution across a hybrid channel: telecom fiber joined to outdoor free-space links of 90 and 750 meters, with the encoding converted all-optically so the junction never reads the key. A close look at what removing the trusted node means for military and critical-infrastructure networks, who gains on each side of the seam, and the engineering and doctrinal distance still separating a rooftop demonstration from a quantum-secure communications procurement.
Entanglement Survives 62 Kilometers of Ordinary Aerial Fiber
A NIST, Joint Quantum Institute and Qunnect team sustained entanglement distribution across a 24-hour trial, at 92.8 percent uptime, over 62 kilometers of noisy aerial telecom fiber, moving quantum key distribution links from bespoke builds toward existing infrastructure.
