We present an analytical study of the time-dependent spectra of a three-level atom in the cascade configuration driven by two intense coherent fields and damped by a broadband squeezed vacuum. We have also studied the influence of the initial state preparation of the atom on the transient spectrum.

In this paper, the influence of imprecise quantum measurement on remote state preparation scheme is investigated. By analyzing the measurement parameters and corresponding errors, we obtain the evolution of output state in the process of remote state preparation. In terms of the fidelity of initial state and output state, the influence of imprecise quantum measurement is discussed. The results of this paper have the reference value for the selection of measurement basis when the quantum measurement on remote state preparation is imprecise.

Over Time

We present a scheme for remote preparing a general two-particle state by two entangled states serving as the quantum communication channel. In this scheme, it is possible for the receiver to perfectly reconstruct the initial state that the sender hopes to prepare with the method of introducing an auxiliary qubit and postselection measurements in the situation of non-maximal entangled quantum channel. Furthermore, we investigate the influence of the dissipation factors on the processing of the remote state preparation when the entangled resources are in the Markovian and non-Markovian noisy environments. It is shown that the fidelity of remote state preparation is decreasing exponentially over time in Markovian environments and attenuating oscillatorily in non-Markovian. However, when the non-Markovian and the detuning conditions are satisfied simultaneously, the fidelity can be preserved at comparative high levels, effectively.
