Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

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

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.

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

Photon blockade is a quintessential phenomenon in quantum optics, wherein a strongly nonlinear system prevents the absorption of additional photons once a single photon is present, effectively ...

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 ...

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 ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...
