Abstract:

With two independent parametric down-converters one can realize an “event-ready” Bell-EPR experiment. Monitoring for sharply coincident idlers results in entangling and pre-selecting the independent signals, which are then fed into an interferometric setup. We give the general conditions for high visibility and particle collection efficiency for Bell-type experiments involving two independent sources. These ideas can also lead to a realizable GHZ experiment.
