N00N-like Interferences from two Thermal Light Souces — •Daniel Bhatti1,2, Anton Classen1,2, Steffen Oppel1, Raimund Schneider1,2, and Joachim von Zanthier1,21Institut für Optik, Information und Photonik, Universität Erlangen-Nürnberg, 91058 Erlangen, Germany — 2Erlangen Graduate School in Advanced Optical Technologies (SAOT), Universität Erlangen-Nürnberg, 91052 Erlangen, Germany

N00N-states have been introduced originally to produce super-resolving interference patterns by use of collective N-photon states propagating along two possible quantum paths [1]. Recent experiments have shown that N independent, incoherently emitting thermal light sources (TLS) can generate similar super-resolving multiphoton interferences when measuring the mth-order intensity correlation function for m = N and if m − 1 detectors are placed at particular positions [2]. Employing the same m − 1 fixed detector positions we reveal that N00N-like interferences of arbitrary order can be generated with merely N = 2 independent TLS, when measuring higher-order intensity correlation functions with m ≥ 2 and at least m − 1 moving detectors. We show that the resulting interference patterns can be interpreted as N00N-like Hanbury Brown and Twiss interferences.
