I have some questions about other possible tests of the EPR Paradox. The base of the paradox is using one entangled particle to gain information about the other. The usual setup discussed involves spin, often photon spin. But what about other measurable attributes of a particle?
If we take the same entangled photons and run them through 2 double slit setups on opposite sides of the source, they should presumably yield 2 interference patterns. Is this new setup clear? We are still observing particles in the singlet state, just not looking at the spin component.
Now, if we cover one of the slits on one side (say the Left), so we know which of the 2 slits the Left particle travels through, the interference pattern disappears on the left. Does this tell us anything about the particle on the Right? Is there some complimentary property that could collasped by such a measurement?
I am trying to imagine that the interference pattern seen on the Right would also disappear if one slit on the Left is covered. Have there been any actual experiments performed with this setup to see what would happen?
Thanks,
