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

Quantum objects are notoriously shifty. Take the photon, for example. The quantum of light can act as a particle one moment, following a well-defined path like a tiny projectile, and a wave the next, ...

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of ...

"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.

A new experiment captures a single parcel of light morphing between wave and particle. Published in the April Physical Review A, the experiment dissects a light pulse associated with a single photon ...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed.

In 1905, Albert Einstein provided an explanation of the photoelectric effect – that various metals emit electrons when light is shined on them – by suggesting that a beam of light is not simply a wave ...

One of the stranger features of the quantum world is that light—even individual photons—can behave as a wave or a particle, depending on how you measure it. But, according to papers released by ...
