Yesterday our paper A quantum imager for intensity correlated photons was published in the New Journal of Physics. NJP is published by the Deutsche Physikalische Gesellschaft and the Institute of Physics. The link to the paper is http://www.iop.org/EJ/abstract/1367-2630/11/1/013001, where you find this abstract:
We report on a device capable of imaging second-order spatio-temporal correlations g(2)(x, τ) between photons. The imager is based on a monolithic array of single-photon avalanche diodes (SPADs) implemented in CMOS technology and a simple algorithm to treat multiphoton time-of-arrival distributions from different SPAD pairs. It is capable of 80 ps temporal resolution with fluxes as low as 10 photons s−1 at room temperature. An important application might be the local imaging of g(2) as a means of confirming the presence of true Bose–Einstein macroscopic coherence (BEC) of cavity exciton polaritons.
This quantum imager may not be a big seller, even at Walmart. According to Gisin and his Swiss crew, you should be able to see entangled photons with ready-to-wear, come-as-you-are eyeballs.
