Squeezed quantum cats

ETH professor Jonathan Home and his colleagues reach deep into their bag of tricks to create so-called 'squeezed Schrödinger cats.' These quantum systems could be extremely useful for future technologies.

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 ...

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 ...

X-rays capture electron 'dance'

(Phys.org)—The way electrons move within and between molecules, transferring energy as they go, plays an important role in many chemical and biological processes, such as the conversion of sunlight to energy in photosynthesis ...

Blackening copper opens new applications

(Phys.org)—Copper is one of the world's most widely used metals. Now researchers at the University of Dundee have found that blackening copper using industry-standard lasers could make it even more adaptable and efficient.

White House uses humor to kill 'Death Star' petition

With the US national debt standing at more than $16 trillion, the White House says it absolutely cannot spend $850 quadrillion on a "Star Wars"-inspired "Death Star" super-weapon.

Record-setting X-ray jet discovered

A jet of X-rays from a supermassive black hole 12.4 billion light years from Earth has been detected by NASA's Chandra X-ray Observatory. This is the most distant X-ray jet ever observed and gives astronomers a glimpse into ...
