How Does Quantum Interference and Wave Trapping Work? A Guide to One of Physics’ Most Elegant Phenomena

Imagine sending a single particle through two doorways simultaneously, only to have it mysteriously vanish when you try to observe which one it actually passed through. This is not magic—it’s quantum interference, one of the most counterintuitive yet fundamental phenomena in physics. At the heart of this mystery lies wave trapping, a process where quantum … Read more
