How do a pair of particles via entanglement “know” what the other particle is doing? Any help is appreciated.
 
Physics news on Phys.org
There is no consciousness here (I would argue). The entangled particle are correlated.

I am curious about other peoples theories of how they remain correlated even when separated by billions of miles. Most of what I have read just says, they act "as one particle". But, this is not satisfying to me because typically part of one particle is proximate to each other (locality).

One thought I came up with (but, perhaps others have too) is the entangled particles retain their relationship to their underlying quantum field. As a result, they remain correlated even when separated by billions of miles.

But, if there is research into this that throws additional light, I am interested too.
