Has this experiment been done?

    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?

    One in which entanglement swapping does not occur on the two photons that go to a particular party.
