I like this site because, even when people ask fundemenal questions ( bone headed ) they are not humiliated, lol, so hear I go.

Could one use the mirror's left on the moon to observe quantum entanglement? Earth based laser,
change phase on the way out, observe the returning photons?

:welcome:

Sure, assuming atmospheric noise was not too great. You can perform phase changing operations on an entangled photon without otherwise causing entanglement to cease.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
