  • Abstract
    The secure transmission of cryptographic keys is demonstrated over a 10 km-long optical fibre channel using a technique called `quantum cryptography´. Single-photon detector noise and nonideal modulator frequency response lead to error rates of ~6% in the transmitted keys that are corrected using publicly agreed key permutations and parity checks
