Multipath correlation interference with a thermal source and quantum logic simulations: a fundamental effect in quantum optics — •Johannes Seiler and Vincenzo Tamma — Institut für Quantenphysik and Center for Integrated Quantum Science and Technology (IQST), Universität Ulm, D-89069 Ulm, Germany
We theoretically demonstrate [1] a novel fundamental effect in quantum optics: the emergence of multipath correlation interference with a thermal source and its ability to simulate the operation of a quantum logic gate known as controlled-NOT gate. In particular, 100%-visibility correlations typical of any Bell state are demonstrated by performing polarization correlation measurements in the fluctuation of the number of photons at the interferometer output. The physics of multiboson interference at the very heart of this proposal can be readily used to simulate on-demand higher-order entanglement correlations in higher-dimension bosonic networks.
