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, ...

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 ...

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 ...
