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

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

A single-photon detector (SPD) is sensitive to incidence of individual quanta of light and has many applications in photonics, such as fluorescence measurements, laser ranging, optical time-domain ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

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 ...

A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...

Laser spectroscopy is a powerful tool for atmospheric gas analysis, yet traditional methods face challenges due to atmospheric turbulence and significant energy loss. While dual-comb spectroscopy ...
