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 ...
A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, ...
"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.
A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...
