Entanglement swapping with PDC sources
Marek Żukowski, Dagomir Kaszlikowski · arXiv (Cornell University) · 1999
We show that the possibility of distinguishing between single and two photon detection events is not a necessary requirement for the proof that recent operational realization of entanglement swapping cannot find a local realistic description. We propose a simple modification of the experiment, which gives a richer set of interesting phenomena.
