Abstract

Interference phenomena are at the origin of many intriguing effects in physics, in particular in the field of quantum optics. Here, we present a novel type of interferometer, which realizes interference in the two-photon component of an incoming laser light. As a consequence, it converts the laser light into a stream of single photons or photon-pairs. In this two-photon interferometer, the beam splitters and the phase shifter of the interferometer are realized using cold atoms, which are trapped and optically interfaced with an optical nanofiber (see Fig. 1.a).
