Remote state preparation under fluctuating electromagnetic field

In this article, we introduce a remote state preparation scheme under fluctuating vacuum electromagnetic field in the presence of a perfectly reflecting boundary. We discuss the influence of vacuum fluctuation, atomic polarization, acceleration and boundary on the reliability of the remote state preparation. It is shown that fidelity decreases with increasing acceleration and evolution time, that is acceleration and vacuum fluctuation cause the fidelity decaying. When the atom is transversely polarizable and near this boundary, fidelity increases with the atom-boundary distance narrowing, that is the presence of boundary can effectively improve the fidelity for this case. Acceleration, atomic polarization and atom-boundary distance give us more freedom to steer the performance of the remote state preparation. The results would be helpful for dealing with quantum information tasks in open quantum system and detecting quantum field effect through quantum information processing method.
