If You Thought Quantum Mechanics Was Weird, You Need to Check Out Entangled Time
Up to today, most experiments have tested entanglement over spatial gaps.
The assumption is that the 'nonlocal' part of quantum nonlocality refers to the entanglement of properties across space. But what if entanglement also occurs across time? Is there such a thing as temporal nonlocality?
The answer, as it turns out, is yes.
