有耗散时的量子态重构

Quantum state reconstruction in the presence of dissipation

H. Moya-Cessa, S. M. Dutra, A. Vidiella-Barranco, J. A. Roversi

摘要:

我们提出了一个现实的方案,以确定量子态的单模腔场,即使它已经开始衰减,由于与环境的耦合。虽然耗散破坏了量子相干性,我们表明,在零温度下,足够的信息仍然是初始状态,在一个可观察的数量,允许其维格纳函数的重建。

英文摘要:

We propose a realistic scheme to determine the quantum state of a single mode cavity field even after it has started to decay due to the coupling with an environment. Although dissipation destroys quantum coherences, we show that at zero temperature enough information about the initial state remains, in an observable quantity, to allow the reconstruction of its Wigner function.
