Simulating Exceptional Non-Hermitian Metals with Single-Photon Interferometry

Operational path-phase complementarity in single-photon interferometry

We examine two setups that reveal different operational implications of path-phase complementarity for single photons in a Mach-Zehnder interferometer (MZI). In both setups, the which-way (WW) information is recorded in the polarization state of the photon serving as a “flying which-way detector”. In the “predictive” variant, using a fixed initial state, one obtains duality relation between the...

Detection of Single Photon Emission by Hanbury-Brown Twiss Interferometry

We prepare a solution of nano-diamond particles on a glass microscope slide with a target concentration of 1 × 10 M. Using a confocal microscope, we observe photons emitted from the particles via excitation from a pulsed 532 nm solid state laser at 840 μW. A Hanbury Brown and Twiss interferometer is used to probe these photons for evidence of antibunching. At this time, we did not observe antib...

Two-Photon Counting interferometry

Two-photon counting (TPC) interferometry has been realized by measuring the electrical current due to two-photon absorption in the space charge layer of a semiconductor detector located at the output port of an interferometer. We apply this technique to study the correlation properties of twin beams issued from parametric fluorescence. We describe in details how the different second-order corre...

Photon versus Hadron Interferometry

Photons and mesons are both bosons and therefore satisfy the same Bose-Einstein statistics. This leads to certain similarities in the corresponding Bose-Einstein correlations which underly photon and hadron intensity interferometry. However there are also important differences between the two effects and these will be analyzed in the following.
