利用压缩光场控制量子动力学模型的退相干

A Quantum Dynamical Mode for the Control of Decoherence Using a Squeezed Reservoir

本文利用压缩算符的性质及相干态的性质,推导了一个量子动力学模型的退相干因子,并且实现了宏观极限下的退相干,随后,我们发现这种系统仪器的耦合对退相干有显剧的影响.

In this paper, we deduce a decoherence term of a quantum dynamical mode using the characteristics of squeezed operators and coherent states, and realize decoherence in macroscopic limits, then we find this kind of system-meter coupling has a dramatic influence on decoherence.
