Everything Is Quantum
summary
Claims that China runs a 2,000 km trusted node quantum network and launched a quantum communications satellite, that fiber QKD tops out near 64 km while a Canary Islands free-space link reached ~144 km, and that a viable crypto-breaking quantum computer could exist in as little as five years for state actors. Demonstrations include a KPN-backed QKD link between The Hague and Rotterdam and plans for a four-node quantum backbone by 2021; work also produces a post-quantum VPN (using Kyber) and upcoming SSH/PGP, with standards expected around 2024 and a needed quantum repeater to scale.
