Scientists aim to build the first graviton detector to explore gravity's quantum nature, despite significant challenges.

Light can do more than illuminate a material. In some cases, it can temporarily change how electrons move through it.

An innovative arrangement employing diverse electronic and optical principles and components leads to precision frequency ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to create compact gamma-ray sources that are simultaneously brighter, sharper, ...
