Entangled photons for quantum based cyber security
summary
Company Quantum Optics Jena builds entangled-photon QKD hardware, claiming a compact 10×8 cm module that produces >1 million entangled pairs/s per mW at ~800 nm with high state fidelity and also offers telecom 1.3–1.5 μm sources for industry. Systems ship as full QKD stacks (sources, detectors via suppliers, key management) and use entanglement instead of QRNGs. Practical limits are fiber losses giving ~50–120 km reach today, with trusted-node networks and satellites in use and quantum repeaters left for future scaling.
