Following scenario: One million entangled photon pairs are created and are sent to Alice's and Bob's laboratory such that Alice receives 1 million photons(or any other large number) of which each is entangled to one of the million photons Bob receives, their laboratories being at a distance to each other. Bob is to just have the 1 million photons run through a double slit and check if there is an interference pattern or not. Also, Bob's laboratory is further away from the point the photons were entangled compared to Alice's laboratory, giving Alice some time to perform some tasks/experiments on the photons reaching her, before the photons reaching Bob go through the double slit. My question is: Can Alice affect if Bob will see an interference pattern or not in any way, by doing any kind of experiments on the 1 million photons reaching her, before the photons reaching Bob go through the double slit? I leave the way of how the photons have been entangled and what kind of experiments Alice could do to affect the pattern Bob will see open to your imagination/expertise. I am only interested to know if Alice could or could not affect the pattern Bob would see.
