Quantum Entanglement on the Moon

[John Hurly]

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?

Sure, assuming atmospheric noise was not too great. You can perform phase changing operations on an entangled photon without otherwise causing entanglement to cease.
