论文摘要
我们基于连续变量量子状态的Wigner函数表示形式开发一种一般形式主义，以描述任意条件操作对多模高斯状态的作用。我们将这种形式主义应用于几个示例，因此显示出它作为模拟量子光学实验的优雅分析工具的潜力。此外，我们还使用它来证明EPR转向是遥远准备Wigner阴性状态的必要条件。
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.
