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

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

Light is usually treated as something simple, a clean beam that either shines or does not. At the quantum level, however, ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

Researchers at the University of Iowa have identified a new way to "purify" photons, a development that could improve both the performance and ...

Researchers have uncovered a method to purify a photon stream that is central to quantum circuitry. University of Iowa ...

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'. When you shine light through almost any transparent material, the gridlock of ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

A new paper suggests that we could search for photons created by gravitational waves. A specific physical response turns gravitons from these waves into photons of electromagnetism. Scientists believe ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University ...
