An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

When two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these patterns ...

(Inside Science) — One of the strangest things about quantum mechanics is that a particle can act like a wave. In particular, in a double-slit experiment, individual particles that are shot through a ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.
