Entanglement and state characterisation from two-photon interference

We have seen that two-photon interference has been widely studied in the last thirty years and that it has been used for different purposes depending on the situation: for example, it is a way to prove the indistinguishability of photons or to highlight the metrological advantage given by NOON state ...

The effects of disorder in strongly interacting quantum systems

Starting with an itinerant ferromagnet, I first use an order-by-disorder approach to show that adding quenched charged disorder to the model generates new quantum fluctuations ...
