论文摘要
纠缠可以修改多粒子系统的干扰模式。我们使用路径积分形式主义分析了多粒子干扰的新例子，以及该现象的一些未开发的方面，通过考虑具有叠加状态下两个可区分的粒子的两缝布置。可以通过比较产品，混合和叠加状态的模式来分别研究纠缠的两个组成部分，多粒子项及其连贯性。这表明在某些有利情况下检测多粒子叠加的方案。此外，用施密特数量测量的纠缠程度的影响的依赖性不是单调。
Entanglement can modify the interference patterns of multi-particle systems. We analyse, using the path integral formalism, a novel example of multi-particle interference and some unexplored aspects of this phenomenon by considering the two-slit arrangement with two distinguishable particles in a superposition state. The two components of entanglement, multiplicity of multi-particle terms and their coherence, can be studied separately by comparing the patterns of product, mixed and superposition states. This suggests a scheme to detect multi-particle superposition in some favourable cases. Moreover, the dependence of the effect on the entanglement degree, measured by the Schmidt number, is not a monotone.
