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

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

(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 ...

More than 200 years ago, the English scientist Thomas Young carried out a famous test known as the “double-slit experiment.” He shone a beam of light at a screen with two slits in it, and observed ...
