Zusammenfassung:2021 Optical Fiber Communications Conference and Exhibition (OFC), 2021, paper F4E.1, pp. 1-3 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.
