A mysterious signal from a powerful gamma-ray burst may reveal how exotic particles and altered physics could let extreme radiation cross the universe

Particles of light cannot be divided into smaller particles, but if you try to snip off the end of one, instead of shortening it multiplies

New theoretical work suggests that the pattern of light emitted by atoms could be used to detect gravitational waves at frequencies outside the range of traditional detectors

Scientists in Japan have developed a new way to instantly detect elusive quantum “W states,” a major milestone for quantum technology. The breakthrough could help unlock faster quantum communication, teleportation, and powerful new computing systems.

Scientists tested a live quantum internet between three locations across New York, inching closer to an unhackable internet.

Researchers at the Niels Bohr Institute have broken a longstanding barrier by managing to send single photons—that can't be copied or split and thus are secure—in the network of optical fibers we already have.…

Scientists have achieved a breakthrough by "distilling" light to eliminate the noise that prevents photonic quantum computers from scaling.
