Bell correlations measured in half a million atoms

(Phys.org)—Physicists have demonstrated Bell correlations in the largest physical system to date—an ensemble of half a million atoms at an ultracold temperature of 25 µK. The presence of Bell correlations indicates that ...

Common perovskite superfluoresces at high temperatures

A commonly studied perovskite can superfluoresce at temperatures that are practical to achieve and at timescales long enough to make it potentially useful in quantum computing applications. The finding from North Carolina ...

Manipulating atoms one at a time with an electron beam

The ultimate degree of control for engineering would be the ability to create and manipulate materials at the most basic level, fabricating devices atom by atom with precise control.

Researchers shed new light on atomic 'wave function'

Physicists have demonstrated a new way to obtain the essential details that describe an isolated quantum system, such as a gas of atoms, through direct observation. The new method gives information about the likelihood of ...

Simple equation directs creation of clean-energy catalysts

New guidelines laid down by Nebraska and Chinese researchers could steer the design of less costly, more efficient catalysts geared toward revving up the production of hydrogen as a renewable fuel.

Team brings subatomic resolution to 'computational microscope'

Scientists have built a "computational microscope" that can simulate the atomic and subatomic forces that drive molecular interactions. This tool will streamline efforts to understand the chemistry of life, model large molecular ...
