A new experiment confirms that angular momentum conservation holds even when a single photon is split into two.

When we look at the world around us, all that we see is thanks to light. It reflects, refracts, and interacts, carrying shape ...

A new theory that explains how light and matter interact at the quantum level has enabled researchers to define for the first time the precise shape of a single photon. Research at the University of ...

If you need to measure the presence of photons down to a very small number of them, you are looking at the use of a photomultiplier, as explained in a recent video by [Huygens Optics] on YouTube. The ...

A new platform developed by Illinois Grainger engineers demonstrates the utility of a ytterbium-171 atom array in quantum ...

The decades-old question of whether humans can see individual photons is on the brink of being answered thanks to advances in quantum optics. A positive result would let us use human observers as ...

In conventional molecular semiconductor solar cells, the conversion of an absorbed photon into electrons and holes ...
