Physicists Entangled Photons in the Lab With Photons From the Sun

Posted by in categories: particle physics, quantum physics

In a classic physics experiment, scientists set up quantum entanglement between sunlight and light generated here on Earth.

The researchers in China, the United States, Germany, and the United Kingdom wondered whether any two particles of light, called photons, could show the spooky interactions governed by the rules of quantum mechanics, even if they originated from vastly distant sources. The experiment was mainly curiosity-driven, but it demonstrates that in the future, researchers might be able to use the Sun as a source of light for quantum mechanics-related purposes.
