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 the 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 link between nonclassicality of quantum states and the nonclassicality of correlations.

被动操作下双模高斯状态的最大形成纠缠

我们量化了被动操作下连续变量状态可实现的最大缠结量(EoF),我们将其称为EoF势。特别地,着眼于两种模式的高斯状态,我们导出了针对特定状态类别的EoF势的解析表达式。对于更一般的状态,我们证明了此数量可以由合成高斯模态所需的最小数量的压缩量上限,该数量称为形成挤压。因此,我们的工作提供了量子态的非经典性与相关性的非经典性之间的联系。
