Yes. That's why it's so weird.

Imagine two dice. There's no sense in which one die has a number until you throw it and one side lands upwards.

With entanglement, you have two dice but they're correlated. For example they may always land opposite sides up.

So if you see the value of one, you also know the value of the other. No matter where it is.

The hard questions are:

1. How does one dice/particle know the other has landed/been measured? This is really just a special case of the unsolved measurement problem, but over larger than usual distances.

2. Where does the entanglement information live? If you look at a single die/particle it has no physical property that shows it's entangled. Individually, entangled and unentangled particles are absolutely identical. So you have a correlation that can't be explained by the structure of each die/particle.

IANAQP but to me this suggests that you're looking at a 4D spacetime projection of an object which exists in some higher and/or more abstract space. So there's a single object in a hypothetical Quantum Space and we're seeing two views of it in our 4D spacetime. Entanglement somehow fixes the projection in a certain orientation.
