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 ...

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

Light and matter can remain at separate temperatures even while interacting with each other for long periods, according to new research that could help scale up an emerging quantum computing approach ...

Earth’s rotation has been measured many times over — but never like this. In a first, scientists used entangled quantum particles called photons to reveal the rate at which the globe spins. The feat ...

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic communications to quantum sensors, the manipulation of photons underpins ...

Light is usually treated as something simple, a clean beam that either shines or does not. At the quantum level, however, every beam is a crowd of individual photons, and even tiny imperfections in ...

A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

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 ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...
