Sort of, but actually more no.

The way the equations in quantum physics work, this just happens, and there isn't any accounting for distance or space. That's just how it is.

Now, that seems to contradict our intuitive understanding of physics. Things can't be just linked like that without some force or information traveling between them.

So there are a few different interpretations of that quantum weirdness:

1. That's the way things really are, and our natural perception that things don't work that way may have helped us evolve to this point, but is actually wrong on the quantum scale

2. There is a hidden variable (the communication part, like a pilot wave) and we just haven't found it yet.

It has to do with the combinations of states in the observable you are measuring (in the photon polarization example above, it would be spin or angular momentum). You have to have some way of setting up the system in the entangled state that you want.
