I understand now. So it's, "can the information be known?" and the answer to that question, whether instrument or human or decision (such as marking the photon), is what creates the entanglement which causes the collapse.
P.S. Everyone - thanks! I get it now. And it's fascinating!
- monktastic1 9y agoBut the entanglement doesn't "cause collapse." If you entangle states A and B, their joint state is in a superposition and will still exhibit interference (given the right experimental setup). It's just that either particle by itself will not.
