Multi-photon coherence and interference — •Sholeh Razavian1,2, Klaus Mølmer3, Jasmin Meinecke1,2, and Harald Weinfurter1,21Department fur Physik, Ludwig-Maximilians-Universitat, Munich, Germany — 2Max-Planck-Institute for quantum optics, Garching, Germany — 3Niels Bohr Institute, Copenhagen, Denmark

The Hong-Ou-Mandel(HOM) effect is a prime example of photon interference in quantum optics and forms the basis for many quantum applications. While HOM interference is a two-photon effect, we are lifting it to the general case, considering multi-photon interference including decoherence effects.

Here we are analyzing polarized photons propagating in integrated waveguide arrays with polarization dependent coupling. With two observables, one for path and one for polarization. The output is a superposition of all the different configurations in a possibly non-classical state.

We analyze multiphoton coincidence measurements and samples from the probability distribution in order to investigate polarization-dependent decoherence of the total quantum state.
