Abstract :
We present a high-security digital-coherent transmission scheme with a QAM-based two-dimensional quantum-noise stream cipher employing amplitude and phase encryption simultaneously and multi-bit encoding with a multi-bit basis state. 40 Gbit/s-480 km and real-time 10 Gbit/s-320 km secure transmissions are demonstrated.
