Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based qubit on a chip for the first time.

Scientists are using trapped ions in cutting-edge experiments to hunt for signs of an undiscovered particle that might help ...

New results published in the journal Physical Review Letters detail how a specially designed metamaterial was able to tip the ...

Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.

All light is made up of waves of electromagnetic radiation. A spectroscope spreads each different wavelength to a different position within a spectrum of light. Music is digitally recorded as circular ...

New observations support the idea that hot, diffuse threads of gas called cosmic filaments connect clusters of galaxies ...

A vast filament of gas stretching across the cosmos may help solve the mystery of the Universe’s missing matter. Astronomers ...

It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make energy-harvesting devices more efficient ...

EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials ...

In this paper, we present a comprehensive channel modeling and characterization study for visible light communications. Our study is based on ray tracing, which allows for an accurate description of ...
