Hi, I have some questions concerning entanglement. 1. If it's possible (theoretically) to simultaneously measure both entangled particles. Then what will the measurements give? 2. The wave function is supposed to hold the info about both entangled particles...it's a superposition. When you apply a measurement on one of the entangled particles, the superposition/wave function/entanglement collapses. So which info do you measure? Does the collapsing of the superposition make the particles go back to there quantum state from before they got entangled (+the state that caused the entanglement to collapse)? 3. Measurement breaks the entanglement, so how can you study entanglement? How can you know particles behave as twins without measuring them? 4. I've heard from another physicist that information transfer demands a classical channel between the particles. And the wave function contains the info about both particles. So then that classical channel is the superposition?
