论文摘要
我们量化了在被动操作下可通过连续变化状态实现的最大形成纠缠量（EOF），我们称为EOF电位。尤其是将重点放在两种模式高斯状态上，我们为特定状态类别的EOF电位提供了分析表达式。对于更一般的状态，我们证明了该数量可以通过合成高斯模式所需的最小挤压量来限制，这是一种称为地层挤压的数量。因此，我们的工作在量子状态的非古典性与相关性的非经典性之间提供了新的联系。
We quantify the maximum amount of entanglement of formation (EoF) that can be achieved by continuous-variable states under passive operations, which we refer to as EoF-potential. Focusing, in particular, on two-mode Gaussian states we derive analytical expressions for the EoF-potential for specific classes of states. For more general states, we demonstrate that this quantity can be upper-bounded by the minimum amount of squeezing needed to synthesize the Gaussian modes, a quantity called squeezing of formation. Our work, thus, provides a new link between non-classicality of quantum states and the non-classicality of correlations.
