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

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

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University ...

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 ...

Carbon nanotubes are moving from lab curiosities to workhorse components in quantum hardware, and one of the most striking examples is their use as single-photon light sources. By exploiting their ...

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

Researchers at the University of Iowa have identified a new way to "purify" photons, a development that could improve both the performance and ...

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 ...

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 ...
