Remote Preparation of Quantum Entangled State in a Non-Markovian Environment

Abstract

We present a practical and general scheme of remote state preparation in the presence of the classical non-Markovian noises, where one of the quantum channels becomes a mixed state. The noises can be modelled as the so-called Ornstein-Uhlenbeck processes. This remote state preparation scheme is more practical than the pure state case in quantum information processing. The fidelity of the remote state preparation is (1 + e −4f(t))/2 and the success probability is 1/2.
