New paper & talk @UFF: Witnessing genuine multi-photon indistinguishability

Daniel Brod and I (Ernesto Galvão) have recently posted a new preprint on the arxiv, the latest result of our long-standing collaboration with the experimental group of Fabio Sciarrino at Sapienza University of Rome. I’ll be giving a talk about it next Friday, April 20th, at 11.00 in room A5-01, come if you can!

The paper describes a way to test whether a set of single-photon sources is producing a state of n genuinely indistinguishable photons, as opposed to some convex combination of states in which effectively less than n photons interfere. As it turns out, this question can be motivated by a simple logic problem, as I explain below. Then I briefly describe how the Rome lab experimentally tested our idea. Read the rest of this entry »
