State-of-the-art of making communication quantum-secure
summary
OpenQKD testbed in Berlin integrates IDQ and Toshiba QKD devices, an HSM as single point of truth, PQC key-exchange over 5G, and optical endpoints; it delivers 1,000–1,800 bits/s key rates per link with QBER ~3% and ~97% visibility, and observes the practical 100 km reach limit. The stack is vendor-agnostic, supports key forwarding via trusted nodes with a PQC overlay, and already secures SRTP/WebRTC/SOCKS5 use cases end-to-end.
