Researchers find a way to purify photons, clearing major hurdles for faster quantum computers and ultra-secure networks.

Teleportation has quietly shifted from pure fantasy to a working laboratory tool, and the latest experiments are starting to ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

Brookhaven National Laboratory and collaborators have developed a new type of lidar—a laser-based remote-sensing ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University ...

A beam of light was sent through a maze of mirrors and detectors. Then scientists changed the setup after the photon had already passed through. Somehow the photon adjusted its behavior as if it had ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

This study presents a novel method for time-resolved fluorescence spectroscopy using entangled photon pairs, enabling rapid, ...

Two-photon imaging and ocular dominance mapping. A. Optical windows for imaging of two macaques. Green crosses indicate the regions for viral vector injections, and yell ...

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries ...

The original version of this story appeared in Quanta Magazine. There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin ...
