论文摘要
Bohr的互补性和Schrödinger的纠缠是量子系统的两个突出的物理特征。在这封信中，我们正式将它们连接起来。众所周知，波颗粒二元性的互补关系仅适用于纯，单量子，量子状态。对于混合状态，波粒量化器永远不会饱和互补关系，甚至可以达到最大混合状态的零。为了充分表征量子，不足以考虑其波颗粒的方面。我们还必须考虑其与其他系统的量子相关性。在这里，我们证明，对于涉及满足文献中标准的可预测性和可见性指标的任何完全互补关系，这些相应的量子相关性是纠缠单调。
Bohr's complementarity and Schrödinger's entanglement are two prominent physical characters of quantum systems. In this letter, we formally connect them. It is known that complementarity relations for wave-particle duality are saturated only for pure, single-quanton, quantum states. For mixed states, the wave-particle quantifiers never saturate a complementarity relation and can even reach zero for a maximally mixed state. To fully characterize a quanton, it is not enough to consider its wave-particle aspect; we have also to regard its quantum correlations with other systems. Here we prove that for any complete complementarity relation involving predictability and visibility measures that satisfy the criteria established in the literature, these corresponding quantum correlations are entanglement monotones.
