The celebrated Hong, Ou and Mandel (HOM) effect is one of the simplest
illustrations of two-particle interference, and is unique to the quantum realm.
In the original experiment, two photons arriving simultaneously in the input
channels of a beam-splitter were observed to always emerge together in one of
the output channels. Here, we report on the realisation of a closely analogous
experiment with atoms instead of photons. This opens the prospect of testing
Bell's inequalities involving mechanical observables of massive particles, such
as momentum, using methods inspired by quantum optics, with an eye on theories
of the quantum-to-classical transition. Our work also demonstrates a new way to
produce and benchmark twin-atom pairs that may be of interest for quantum
information processing and quantum simulation.
