Tuning up Rydberg atoms for quantum information applications

Rydberg atoms, atoms whose outermost electrons are highly excited but not ionized, might be just the thing for processing quantum information. These outsized atoms can be sustained for a long time in a quantum superposition ...

This ESA test bench is usually shrouded in darkness, except for the laser beam being projected across it.

More efficient transformer materials

Almost every electronic device contains a transformer. An important material used in their construction is electrical steel. Researchers have found a way to improve the performance of electrical steel and manufacture it more ...

Compact proton therapy for fight against cancer

The future face of modern-day anti-cancer therapy based on charged particles like protons could potentially involve using laser accelerators. However, these facilities will need to be reduced in terms of both size and cost ...

New laser technology could divert lightning strikes

(Phys.org) —Optical scientists at the University of Arizona and the University of Central Florida have developed a technology capable of sending high-intensity laser beams through the atmosphere much farther than was possible ...

Physicists quantify temperature changes in metal nanowires

(Phys.org) —Using the interaction between light and charge fluctuations in metal nanostuctures called plasmons, a University of Arkansas physicist and his collaborators have demonstrated the capability of measuring temperature ...
