• Abstract: The interference phenomenon of light is a common but most important effect in physics. In this article, we compare and analyse the interference effects of both coherent and incoherent light; in particular, the interference of spatially incoherent light sources is described. Thermal light and a two-photon entangled source may both be regarded as incoherent sources which can generate similar second-order interference effects, but their underlying physics is quite different. First-order interference can be realized with both spatially coherent and incoherent sources in the same well-designed experimental setup, but exhibit different interference patterns; their different interference mechanisms will also be clarified.

• Optical interference by amplitude measurement [4.805271817497192]
  We make a comprehensive study in both theory and experiment of a technique by homodyne measurement of field amplitudes to reveal interference. This works for both classical and quantum fields even though there exists distinguishability in the interfering paths of light. This technique is particularly useful for recovering interference in unbalanced interferometers with path-imbalance beyond coherence length of the input field.

• 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.

  We study the impact of distinguishability and mixedness -- two fundamental properties of quantum states -- on quantum interference. We show that these can influence the interference of multiple particles in different ways, leading to effects that cannot be observed in the interference of two particles alone.

  Quantum asymmetry is a physical resource which coincides with the amount of coherence between the eigenspaces of a generator. We show that the asymmetry may emphincrease as a result of a emphdecrease of coherence inside a degenerate subspace.

  We investigate, in a four photon interference experiment in a laser-written waveguide structure, how symmetries control the suppression of many-body output events of a $J_x$ unitary. We show that totally destructive interference does not require mutual indistinguishability between all, but only between symmetrically paired particles.

• Multipath Wave-Particle Duality in Classical Optics [0.0]
  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.
