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 ...

Quantum sensors are fascinating instruments that reveal nature to us in ways that were unthinkable just a few years ago. These are relatively small devices that help investigate items of scientific ...

A Rydberg atom is an excited atom with one or more electrons that have a very high principal quantum number, n. The higher the value of n, the farther the electron is from the nucleus, on average.

Researchers have discovered giant Rydberg molecules with a bond as large as a red blood cell. Determining how Rydberg molecules interact is important because Rydberg atoms are a key ingredient in atom ...

Rydberg atom–based electrometry exploits the exaggerated electric dipole moments of atoms in highly excited electronic states to achieve precise, traceable measurements of radio‐frequency and ...

WEST LAFAYETTE, Ind. - A Purdue University physicist has observed a butterfly Rydberg molecule, a weak pairing of two highly excitable atoms that he predicted would exist more than a decade ago.

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 ...

Quantum computers of the future could operate via the energy transitions of excited atoms, or even from pure light, if a rapidly growing area of atomic physics continues to meet with success, writes ...
