Rydberg State

Researchers have discovered a new method for correcting errors in the calculations of quantum computers, potentially clearing a major obstacle to a powerful new realm of computing.

The energy transport between atoms and molecules is the basis of all life. Such transport is based on interatomic forces known as the dipole-dipole interaction. Prof. Dr. Herwig Ott's research group at Technische Universität Kaiserslautern (TUK) has now succeeded in reproducing such a transport mechanism in a disordered system. For this purpose, the researchers experimentally observed the quantum mechanical…

The Rydberg state is prevalent across various physical mediums such as atoms, molecules, and solid materials. Rydberg excitons, which are highly energized, Coulomb-bound electron-hole pair states, were initially identified in the 1950s within the semiconductor material, Cu2O. In a study published

The discovery of room-temperature time crystals could radically extend the lifespan and stability of quantum states.

Scientists have looked through the quantum fog and discovered an entirely new way to measure the passage of time.

Introduction Quantum researchers require access to different types of quantum hardware from digital, also known as gate-based, quantum processing units (QPUs) to analog devices that are capable of addressing specific problems that are hard to solve using classical computers. Today, Amazon Braket, the quantum computing service from AWS, continues to deliver on its commitment to […]

Physicists have learned to manipulate electrons in gigantic Rydberg atoms with such precision they can create 'synthetic dimensions' where the system acts as if it had extra spatial dimensions, which are important tools for quantum simulations.

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, first discovered in the semiconductor material Cu2O in the 1950s.

Researchers at the 5th Physical Institute of the University of Stuttgart have verified a novel binding mechanism forming a molecule between a tiny charged particle and a gigantic (in molecular terms) Rydberg atom. The scientists observed the molecule with the help of a self-built ion microscope. The results are published in Nature.

A dissipative time crystal is a phase of matter characterized by periodic oscillations over time, while a system is dissipating energy. In contrast with conventional time crystals, which can also occur in closed systems with no energy loss, dissipative time crystals are observed in open systems with energy freely flowing in and out of them.

A team of physicists has produced pure trilobite molecules in rubidium over a wide range of frequencies and characterize their binding energies, lifetimes, and dipole moments.

A startup company has upped its qubit count by an order of magnitude in two years.

Researchers have demonstrated that a solid can exhibit an enhanced nonlinear optical phenomenon usually seen only in cold atomic gases.

Researchers have adapted their atom-based radio receiver to display live TV and video games.

We demonstrate the ability to receive live color analog television and video game signals with the use of the Rydberg atom receiver. The typical signal expected for traditional 480i National Televi...

Theorists predict that an atomic gas could be magnetized using only lasers, something that could provide a noninvasive way to quickly manipulate the magnetic properties of the gas.
