论文摘要
波粒二元性的互补关系仅针对纯，单量子量的量子状态饱和。对于完全不连贯的状态，众所周知，波浪和粒子量词可以达到零，因此无法获得有关系统的波和粒子方面的信息。这意味着信息正在与另一系统共享，并且可以将量子相关性视为负责量子纯度的丧失，前提是量子量是多部分纯量子系统的一部分。在本文中，通过探索双方和三方纯量子状态的纯度，我们表明可以获得完全互补关系。此过程使我们能够创建一个通用框架，以获取属于纯状态的任意多目标量子系统的子系统的完整互补关系。此外，在一些简单的示例中，我们表明，如果更改可预测性度量，则还必须更改相关度量，以便为纯粹的病例获得完整的互补关系。
Complementarity relations for wave-particle duality are saturated only for pure, single-quanton, quantum states. For a completely incoherent state, it is known that wave and particle quantifiers can reach zero, and hence no information about the wave and particle aspects of the system can be obtained. This means that the information is being shared with another systems, and quantum correlations can be seen as responsible for the loss of purity of the quanton, provided that the quanton is part of a multipartite pure quantum system. In this paper, by exploring the purity of bi- and tri-partite pure quantum states, we show that it is possible to obtain complete complementarity relations. This procedure allows us to create a general framework for obtaining complete complementarity relations for a subsystem that belongs to an arbitrary multi-partite quantum system in a pure state. Besides, by some simple examples, we show that if the predictability measure is changed then the correlation measure must also be changed in order to obtain complete complementarity relations for pure cases.
