• Abstract: Correlated interference is calculated for a microscopic particle retro-reflecting from two spatially separated scatterers that are free to move, all three of which are treated as quantum bodies: the positions of the particle traversing this one-dimensional interferometer and those of the interferometer components are all uncertain. Interference in a measurement of only the particle is shown to disappear for microscopic yet appear for mesoscopic scatterers, contrary to that of a quantum-classical transition. A measurement of this threshold can verify quantum correlations in many-body systems by measuring only the retro-reflected microscopic particle. The decoherence of a mesoscopic scatterer is determined by this threshold without it having to traverse slits or beamsplitters.

  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.

  We experimentally investigate the possibility that an individual neutron moving through a two-path interferometer may actually be physically distributed between the two paths. Results show that individual particles experience a specific fraction of the magnetic field applied in one of the paths, indicating that a fraction or even a multiple of the particle was present in the path before the interference of the two paths was registered.

• Unambiguous joint detection of spatially separated properties of a single photon in the two arms of an interferometer [0.0]
  The quantum superposition principle implies that a particle entering an interferometer evolves by simultaneously taking both arms. For a fixed state measured at the output port, certain particle properties can be associated with only one or the other path. We report observation of the spatial and polarization degrees of freedom of a single photon in the two arms of an interferometer.

  Hong-Ou-Mandel (HOM) effect can lead to a perfect suppression of two-particle coincidences between the output ports of a balanced beam splitter. In this work, we demonstrate experimentally that the two-particle coincidence statistics of two bosons can instead be seamlessly tuned to substantial enhancement. Our findings reveal a new approach to harnessing non-Hermitian settings for the manipulation of multi-particle quantum states.

We show that totally destructive interference does not require mutual indistinguishability between all, but only between symmetrically paired particles.
