NATIVE CONTINUOUS-VARIABLE QUANTUM REPEATER

Abstract: a first device receives a data qumode and at least one auxiliary qumode from a second device. the data qumode and the auxiliary qumode(s) were entangled at the second device. the first device entangles the data qumode and the auxiliary qumode(s) and measures the auxiliary qumode(s). measuring the auxiliary qumode(s) generates an indication of an error channel experienced by the data qumode. the first device applies an error correction to the data qumode based on the indication of the error channel, and generates a corrected data qumode.
