Monte Carlo simulation of photonic state tomography: a virtual Hanbury Brown and Twiss correlator
نویسندگان
چکیده
This paper provides a theoretical background for the simulations of particular quantum optics experiments, namely, photon intensity correlation measurements. A practical example, adapted to polarisation-entangled photon pairs emitted from a quantum dot, is presented. The tool, a virtual Hanbury Brown and Twiss correlator, simulates polarisation-resolved the second-order correlation functions, which then can be used in a photonic state tomography procedure—a full description of a light source’s polarisation state. This educational tool is meant to improve general understanding of such quantum optics experiments.

متن کاملDetection 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...

متن کاملWitnessing Entanglement of Epr States with Second-order Interference
The separability of the continuous-variable EPR state can be tested with Hanbury-Brown and Twiss type interference. The second-order visibility of such interference can provide an experimental test of entanglement. It is shown that time-resolved interference leads to the Hong, Ou and Mandel deep, that provides a signature of quantum non-separability for pure and mixed EPR states. A Hanbury-Brow...
