Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

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

A persistent group of scientists at the University of Warsaw have accomplished the impossible by creating a hologram of a solitary particle of light, reports Business Insider.

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

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, ...

The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring ...

A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range ...

New research has unveiled a new advancement in Light Detection and Ranging (LIDAR) technology, offering unparalleled sensitivity and precision in measuring the distance of remote objects. This ...

For the first time, scientists have observed quantum interference—a wavelike interaction between particles related to the weird quantum phenomenon of entanglement—occurring between two different kinds ...
