AI总结:

本文提出通过一维开放量子谐振子级联制备纯高斯态的方法,无需谐振子间直接相互作用哈密顿量,实验上具有优势,并以双模压缩态制备为例说明理论。

摘要:

本文提供了一种制备线性量子系统中纯高斯态的替代方法。证明任何纯高斯态均可通过一维开放量子谐振子的级联生成,而无需这些谐振子间存在直接相互作用哈密顿量。从实验角度看,这种方法具有优势。通过双模压缩态的制备示例来说明该理论。

英文摘要:

This paper provides an alternative approach to the problem of preparing pure Gaussian states in a linear quantum system. It is shown that any pure Gaussian state can be generated by a cascade of one-dimensional open quantum harmonic oscillators, without any direct interaction Hamiltonians between these oscillators. This is physically advantageous from an experimental point of view. An example on the preparation of two-mode squeezed states is given to illustrate the theory.
