Demonstration of Probabilistic Constellation Shaping for Continuous Variable Quantum Key Distribution

Demonstration of Probabilistic Constellation Shaping for Continuous Variable Quantum Key Distribution

We demonstrate, for the first time to our knowledge, continuous-variable quantum key distribution using probabilistically-shaped 1024-QAM and true local oscillator, achieving 38.3Mb/s secret key rate over 9.5km, averaged over the transmission time of 100 blocks.
