Hi there,

I'm looking for an experiment performed to date that:
(a) creates two pairs of entangled photons (in the same entangled state);
(b) subjects one photon of each pair to a bell-state measurement or decides to perform a separable state measurement on the two photons (so they don't become entangled)
(c) that (b) is randomly decided
(d) the two photons left are then measured (which indicate they're entangled; if not, they remain entangled as when they're produced).

Basically an experiment opposite of http://www.nature.com/nphys/journal/v8/n6/full/nphys2294.html, except both separable and bell-state measurements are performed on the two photons going to Victor (and that is randomly decided).

What is a separable state measurement?

What is a separable state measurement?
One in which entanglement swapping does not occur on the two photons that go to a particular party.
