Is nonlocality inherent in all identical particles in the universe?

What is interaction, and when does it occur? Intuition suggests that the necessary condition for the interaction of independently created particles is their direct touch or contact through physical force carriers. In quantum ...

How the quantum Zeno effect impacts Schroedinger's cat

You've probably heard about Schrödinger's cat, which famously is trapped in a box with a mechanism that is activated if a radioactive atom decays, releasing radiation. The act of looking in the box collapses the atom's wave ...
