In an achievement that could help enable fast quantum computers, University of Michigan physicists have built a better Rydberg atom trap. Rydberg atoms are highly excited, nearly-ionized giants that can be thousands of times ...

It is a situation familiar from one's own living environment: relations between neighbours can be intense, yet also characterised by sensitivities. Complex quantum systems can be imagined in a similar way – especially when ...

Rydberg atoms are excited atoms that contain one or more electrons with a high principal quantum number. Due to their large size, long-range dipole-dipole interactions and strong coupling to external fields, these atoms have ...
Scientists at the MPQ (Garching) and MPIPKS (Dresden) have developed a novel technique to let atoms interact over large distances.

Rydberg atoms and molecules are characterized by having one or more electrons in highly excited bound states. Such atoms and molecules are said to be in "Rydberg states" and are also called "hollow" atoms and molecules. Rydberg ...

There was a lot of excitement last year when the LIGO collaboration detected gravitational waves, which are ripples in the fabric of space itself. And it's no wonder – it was one of the most important discoveries of the ...
