Aharonov–Vaidman bomb

The Aharonov–Vaidman bomb experiment is a thought experiment in quantum physics that demonstrates how particles, like photons, can be affected by potential interactions even without direct contact. Imagine detecting a sensitive bomb that explodes if it interacts with a photon; using quantum techniques, scientists can sometimes determine whether the bomb is functional without triggering it. This showcases a phenomenon called "interaction-free measurement," where information about an object is gained without directly interacting with it, highlighting the strange, non-intuitive nature of quantum mechanics.
