条件非高斯量子态制备

Conditional non-Gaussian quantum state preparation

Mattia Walschaers, Valentina Parigi, Nicolas Treps

摘要:

基于连续变量量子态的Wigner函数表示,我们发展了一种通用的形式,来描述任意条件操作对多模高斯态的作用。我们应用这种形式主义的几个例子,从而显示其作为一个优雅的分析工具,模拟量子光学实验的潜力。此外,我们还使用它来证明EPR转向是远程准备Wigner负态的必要条件。

英文摘要:

We develop a general formalism, based on the Wigner function representation of continuous-variable quantum states, to describe the action of an arbitrary conditional operation on a multimode Gaussian state. We apply this formalism to several examples, thus showing its potential as an elegant analytical tool for simulating quantum optics experiments. Furthermore, we also use it to prove that EPR steering is a necessary requirement to remotely prepare a Wigner-negative state.
