WebPhoton antibunching. A typical setup for probing photon antibunching is a Hanbury-Brown and Twiss (HBT) interferometer, which comprises of a beam splitter and two photon detectors. The output of the photon detectors is time-correlated to measure the number of coincidence counts. WebIt is shown by example that sub-Poissonian photon-counting statistics need not imply photon antibunching, but can be accompanied by photon bunching, i.e., by the tendency of two photons to be close together more frequently than further apart. Some comments on the relation between antibunching and sub-Poissonian statistics are made.

Photon antibunching generally refers to a light field with photons more equally spaced than a coherent laser field, a signature being signals at appropriate detectors which are anticorrelated. More specifically, it can refer to sub-Poissonian photon statistics, that is a photon number distribution for which … See more The variance of the photon number distribution is Using commutation relations, this can be written as See more Spatial antibunching has been observed in photon pairs produced by spontaneous parametric down-conversion.

Single atoms, ions, molecules, or solid state emitters display antibunching of photons, while classical thermal sources exhibit photon bunching. Here we demonstrate a light source in free …
WebDec 16, 2014 · Photon antibunching is a quantum phenomenon typically observed in strongly nonlinear systems where photon blockade suppresses the probability of detecting two photons at the same time. Antibunching has also been reported with Gaussian states, where optimized amplitude squeezing yields classically forbidden values of the intensity …
