Entangled particles

  1. Oct 31, 2013 #1
    Dear Learned Physicists,

    can anyone educate me on:

    is it possible to distinguish entangled particles before and after interaction in theory?

    what I'm trying to find out is, if two entangled particles can be separated and one interacted with to produce a result at the other end, such that the other particle can produce a measurement but only after the first one is interacted with.

    I hope I am comprehensible above!

    No, it is not possible to determine if Alice has been measured by looking at Bob. The Heisenberg Uncertainty Principle applies to the system, and that limits the amount of information which you can obtain.
