Quantum cipher based on phase inversion
Published 3 Nov 2018 in quant-ph | (1811.01930v1)
Abstract: We present a quantum version of a cipher used in cryptography where the message to be communicated is encoded into the relative phase of a quantum state using the shared key. The encoded quantum information carrying the message is actually sent to the recipient over a quantum channel, assuming the proper secrecy of shared key between peers.
