- Abstract: 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.

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.

Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems.
We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons.
We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

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.

Two-particle interference is not as easy to define as its single particle counterpart, and the realization that it involves interference of two-particle amplitudes came much later.

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.

It is assumed that distinguishing information in the preparation, evolution or measurement of a system is sufficient to destroy interference.
For more than three independent quantum particles, distinguishability of the prepared states is not a sufficient condition for multiparticle interference to disappear.
