Interference effects produced by independent quantum sources are investigated, when the state of the field is not describable as a simple mixture of coherent states. The results of classical and quantum-mechanical calculations are compared. Whereas correlation effects are predicted both classically and quantum mechanically when the sources have random phases, there are important differences when the number of atoms is small. In particular, when each source consists of just one atom, the joint probability of detecting two photons at two different points in the receiving plane is found to vanish when the distance between them is an odd number of half fringes. Finally it is shown that when the number of atoms of each source is subject to Poisson fluctuations, one recovers the solution given by classical optics for thermal light, no matter how weak the sources may be on the average.read more

Photonic Boson Sampling in a Tunable Circuit

TL;DR: The central premise of boson sampling was tested, experimentally verifying that three-photon scattering amplitudes are given by the permanents of submatrices generated from a unitary describing a six-mode integrated optical circuit.

Real-world two-photon interference and proof-of-principle quantum key distribution immune to detector attacks.
TL;DR: The first proof-of-principle implementation of a new quantum-key-distribution protocol that is immune to any such attack is reported, and the feasibility of controlled two-photon interference in a real-world environment is established.

Multiparticle Interferometry and the Superposition Principle
TL;DR: Superposition may be the only true quantum mystery, but in multiparticle systems the principle yields phenomena that are much richer and more interesting than anything that can be seen in one-particle systems as discussed by the authors.
