Abstract

Real-time CV-QKD receiver achieves peak 2.9 Mbit/s secret-key-rates over 12.8 km of fiber, while co-propagating 15 classical channels, separated 1 nm from the quantum signal. Performance degrades at higher launch powers due to crosstalk.

Real-time CV-QKD Bob achieves peak 0.65 Mbps secret key rates over 25.7 km of fiber while co-propagating 14 adjacent classical channels. Performance degrades at higher classical launch powers due to higher excess noise from crosstalk and possible nonlinear optical effects.

We show a real-time CV-QKD receiver realization over a turbulent optical free-space channel with secret key rates up to 2.2 Mbit/s. The real-time GPU receiver evaluated quantum signal integrity under various turbulence scenarios, emulating an 800 m urban terrestrial FSO link.

We study the impact of in-band ASE noise on the performance of CV-QKD over 10 km of fiber. We demonstrate co-propagation of CV-QKD and 3.5 Tbit/s classical coherent channels and show stable key generation over 48 hours.
