Quantum Key Distribution and the Future of Encryption
summary
BT, Toshiba and NPL send quantum keys over 26 km of live, multiplexed fiber (four 10G channels) using a BB84-derived protocol called T12, detecting photons by timing and bundling QKD with AES in counter mode to get about 160 kbps of key material; distance limits look on the order of ~100 km without trusted stations, attacks fail thanks to the no-cloning principle, and lab proofs (Shor/Grover demos, four-photon factoring of 15) show real quantum threats to RSA.
