Quantum technologies, systems that operate leveraging quantum mechanical effects, have the potential to outperform classical technologies in some specific tasks. Over the past decades, some ...

The Rydberg state is widespread in a variety of physical platforms such as atoms, molecules, and solids. In particular, Rydberg excitons are highly excited Coulomb-bound states of electron–hole pairs, ...

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and ...

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 ...

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 ...

The possibility to exactly solve quantum mechanical problems such as the hydrogen atom is based on the existence of symmetries from which constants of motion arise, reducing the degrees of freedom and ...

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 ...

A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the University of Warsaw has developed a new type of all-optical radio receiver based on the fundamental ...
