AI 中文摘要
最近研究表明，满足众所周知的Englert-Greenberger-Yasin不等式的杨氏双缝干涉测量中所体现的波粒二象性，遵循一个涉及相干性、可预测性以及相当令人惊讶的纠缠的普遍三重关系。在本工作中，我们明确证明了在量子诱导相干干涉仪中三重关系的持续性，而经典配置则恢复了众所周知的二象性不等式。此外，我们探索了诱导相干干涉仪中相干性和纠缠的起源，以及控制它们的方法。我们表明，在我们的装置中，路径不可区分性（或源的固有不可区分性）在影响干涉和纠缠方面起着互补作用。我们明确揭示了经典和量子版本的诱导相干干涉仪中相干性的本质。
英文摘要
The wave-particle duality that manifests in the Young's double-slit interferometry satisfying the well known Englert-Greenberger-Yasin inequality has recently been shown to obey a universal triality relation involving coherence, predictability and rather surprisingly entanglement. In the present work, we explicitly demonstrate the persistence of the triality relation in the quantum induced coherence interferometer and the classical configuration recovers the well known duality inequality. Furthermore, we explore the origin of coherence and entanglement, in the induced coherence interferometer, and means to control them. We show that path indistinguishability (or intrinsic indistinguishability of the sources) in our setup plays a complementary role in influencing both interference and entanglement. We bring out manifestly the nature of coherence in both classical and quantum versions of induced coherence interferometers.
