Physicists have long recognized the value of photonic graph states in quantum information processing. However, the difficulty ...

Two physicists at the University of Konstanz are developing a method that could enable the stable exchange of information in quantum computers. In the leading role: photons that make quantum bits "fly ...

Scientists working on CERN’s Compact Muon Solenoid (CMS) experiment have published the latest data in their search for a long-lived exotic particle known as the dark photon. Dark photons (also called ...

Physicists have manipulated individual particles of light, photons, under ultra-stable laboratory conditions. They split a solitary photon into two distinct lower-energy entities, observing with ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.

Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

Researchers have discovered that superconducting nanowire photon detectors can also be used as highly accurate particle detectors, and they have found the optimal nanowire size for high detection ...
