Lets say I create a pair of entangled photons. I then shoot one of the photons through a semi-silvered(semi-reflecting) mirror. one(or both) of the photons are reflected, and (or) one (or both) of the photons penetrate/pass through the mirror. will either one of or both of the actions/interactions detangle the photons in question? (see image for details)

2If you can resolve the change in state (position, momentum) of the mirror, then yes, but this is highly impractical in most scenarios – Quantum Mechanic Sep 09 '21 at 19:57

@QuantumMechanic so more likely the photons will remain entangled? – RhinoPak Sep 09 '21 at 20:00

1Yes. See some of the related questions, they're pretty intriguing. Also, eg https://physics.stackexchange.com/q/94416/291677 – Quantum Mechanic Sep 09 '21 at 20:01
