AbstractA real quantum system is unavoidably affected by external environment, which would produce noise or decoherence, and reduce the efficiency of quantum communication in realistic circumstance. In this paper, we present a noisy deterministic secure quantum communication (DSQC) scheme. We find that fidelity has close relation with quantum coherence and declines to a stable value with decoherent time. Small two-atom distance can improve the fidelity and coherence, and a reflecting boundary can effectively inhibit fidelity and coherence from degradation under the effect of vacuum fluctuation. Our study would be helpful to promote the communication efficiency of open quantum system.Graphical abstract
