FROSTI is a new adaptive optics system that precisely corrects distortions in LIGO’s mirrors caused by extreme laser power.

A tiny device that entangles light and electrons without super-cooling could revolutionize quantum tech in cryptography, ...

An exponential increase in the number of satellites placed in low-Earth orbit has brought advances in telecommunications ...

Quantum communication is edging closer to reality thanks to a breakthrough in teleporting information between photons from ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Nano-optics, by bridging the gap between classical optics and nanotechnology, explores light at dimensions smaller than its wavelength. It leverages phenomena like plasmonics, near-field optics, and ...

Andreas Fichtner strips a cable of its protective sheath, exposing a glass core thinner than a hair — a fragile, 4-kilometer-long fiber that’s about to be fused to another. It’s a fiddly task better ...

An effect first observed decades ago by Nobel laureate Arthur Ashkin has been used to fine tune the electrical charge on ...

Built from a single erbium atom, a hybrid quantum bit encodes data magnetically and beams it through fiber-optic wavelengths.
