Propagation of transverse intensity correlations of a two-photon state
D. S. Tasca, S. P. Walborn, F. Toscano +2
The propagation of transverse spatial correlations of photon pairs through arbitrary first-order linear optical systems is studied experimentally and theoretically using the fracti…

Detection of transverse entanglement in phase space
D. S. Tasca, S. P. Walborn, F. Toscano +1
Transverse entanglement between pairs of photons can be detected through intensity correlation measurements in the near and far fields. We show theoretically and experimentally tha…
