My understanding of the linked PDF is that : the usual interference pattern is NOT observed for the right particles if the left stream of particles are just left alone; but if the left stream of particles (which-path information) are quantum erased, the the usual interference pattern can be...

In the delayed choice experiment the original photon is down-converted after it has passed the silt. In my scenario, the original photon is down-converted way way before the right particle passes the slit. Does that make a difference?

I create 1000 pairs of entangled particles and let them travel very far away. Then I let the 1000 right particles pass through a double slit experiment. At the time when the right particle has passed the slit, but not yet hit the screen, I can choose to detect the 1000 left particles. If I...

What if: 1) we put a swtich gate on the bottom slit. The bottom slit is normally closed, but we time it so we open it just before a photon/electron MAY arrive. so far this will yeild the same result as traditional experiment? 2) usually the two slits are close by, but we move it very...
