When we look at the world around us, all that we see is thanks to light. It reflects, refracts, and interacts, carrying shape and depth from the objects it touches. But what about light itself?

A new platform developed by Illinois Grainger engineers demonstrates the utility of a ytterbium-171 atom array in quantum networking. Their work represents a key step toward long-distance quantum ...

Abstract: Every single photon carries information in position, time, etc. Single-photon devices are now demonstrated and available in several CMOS technologies, but the needed circuits and ...

Physicists have, for the first time, shown that even a single photon obeys one of nature’s strictest rules: conservation of angular momentum. Achieved only once in a billion attempts, this needle-in-a ...

Greenfield-based Photon Automation Inc., which produces automation and robotics systems for advanced manufacturing companies, is expanding with the launch of a new division. Photon Energy will provide ...

Single photons in the mid-infrared can reveal faint galaxies or carry fragile quantum signals across space. They are valuable in astronomy, quantum communication, and even medical imaging. But ...

Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" excitons emit light and are therefore accessible, dark excitons are ...

Researchers at Colorado State University have developed a new photoredox catalysis system that uses visible light mimicking photosynthesis to drive energy-intensive chemical reactions at room ...

Recent work suggests that a single photon might be detected in more than one spot simultaneously. Some see this as a reason to reconsider the idea of alternate universes interacting behind the scenes.
