• Title: Multipath Wave-Particle Duality in Classical Optics
• Authors: Bibhash Paul, Sammi Kamal, Tabish Qureshi
• Abstract summary: In classical optics, the visibility of interference, in a two-beam light interference, is related to the optical coherence of the two beams. A wave-particle duality relation can be derived using this mutual coherence. New definitions of interference visibility and path distinguishability have been introduced, which lead to a duality relation for multipath interference.

• Abstract: It is well known that in classical optics, the visibility of interference, in a two-beam light interference, is related to the optical coherence of the two beams. A wave-particle duality relation can be derived using this mutual coherence. The issue of wave-particle duality in classical optics is analyzed here, in the more general context of multipath interference. New definitions of interference visibility and path distinguishability have been introduced, which lead to a duality relation for multipath interference. The visibility is shown to be related to a new multi-point optical coherence function.

• Entanglement-induced collective many-body interference [62.22849132943891]
  We propose an interferometric setting through which N-particle interference can be observed, while any interference of lower orders is strictly suppressed. We experimentally demonstrate this effect in a four-photon interferometer, where the interference is nonlocal, in principle. A joint detection of all four photons identifies a high-visibility interference pattern varying as a function of their collective four-particle phase, a genuine four-body property.

• Dissipative stabilization of maximal entanglement between non-identical emitters via two-photon excitation [49.1574468325115]
  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

• Influence of polarization and the environment on wave-particle duality [0.0]
  Wave-particle duality ascribes mutually exclusive behaviors to quantum systems that cannot be observed simultaneously. Here, we use quantum information-theoretic tools to derive quantifiers of two properties, which account for the combined influence of path probability and polarization. The derived quantities can work as probes in the study of open quantum dynamics.

• Predictability, Distinguishability and Entanglement [0.0]
  Recent times have seen a spurt of research activity focused on "completing" certain wave-particle duality relations using entanglement or polarization. Quantum origins of these results are explored here, in the more general framework of multipath quantum interference. Results of this study show that the two duality relations are quantitatively connected via entanglement.
