Abstract: We experimentally demonstrate a 250MHz repetition rate Gaussian-modulated coherentstate CVQKD with local local oscillator implementation which is capable of realizing record 14.2 Mbps key generation in the asymptotic regime over 15km of optical fiber.

“…Concepts employing a receiver-side LO [31][32][33][34][35][36][37][38][39][40][41][42][43][44], as it is commonly seen in telecom-based coherent transceivers, have gained significant attention during recent years. Challenges such as the optical carrier synchronization of now independent optical sources at transmitter and receiver have been solved through incorporation of auxiliary training information and powerful signal processing resources.…”

“…Table II compares the obtained results for various CV-QKD systems. The highest transmitted symbol rates are obtained for CV-QKD systems employing continuous training information multiplexed in frequency and quantum heterodyne detection in the baseband, coherent intradyne reception [38,[40][41][42].…”
