A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing quantum-classical transition.

MIT physicists have recreated the most iconic experiment in quantum physics — this time with individual atoms acting as the slits and single photons barely grazing past. Their results have firmly ...

Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

Scientists have introduced a groundbreaking form of quantum entanglement known as frequency-domain photon number-path entanglement. This leap in quantum physics involves an innovative tool called a ...

Driving late at night, you come upon a red light and stop the car. You lift your hand wearily to block the red glow streaming through your windshield. Suddenly, both the green and yellow lights come ...
