Now, in a recent study published in Physical Review Letters, Rey and JILA and NIST Fellow James K. Thompson, along with graduate student Sanaa Agarwal and researcher Asier Piñeiro Orioli from the University of Strasbourg, studied atom-light interactions in the case of effective four-level atoms, two ground (or metastable) and two excited levels arranged in specific one-dimensional and two-dimensional crystal lattices.

If you’d like to solve a math problem on a good old-fashioned chalkboard, you want the board clean and free of any previous markings so that you have space to work. Quantum computers have a similar need for a clean workspace, and a team including scientists at the National Institute of Standards and Technology (NIST) and University of Maryland have found an innovative and effective way to create and maintain it.

Researchers from the National University of Singapore (NUS) have recently achieved a significant breakthrough in the development of next-generation carbon-based quantum materials, opening new horizons for advancements in quantum electronics.

Scientists led by Tobias Kippenberg at EPFL have now achieved the long-sought goal: they successfully prepared six mechanical oscillators in a collective state, observed their quantum behavior, and measured phenomena that only emerge when oscillators act as a group. The research, published in Science, marks a significant step forward for quantum technologies, opening the door to large-scale quantum systems.

To better understand these findings, JILA and NIST Fellow Ana Maria Rey and her theory team collaborated with an international team of experimentalists. The theorists found that atoms in free space can only partially synchronize their emission, suggesting that the free-space experiment did not observe th

In a study published today in Nature Communications, researchers from the Quantum Magnetism group in the Department of Physics have developed an innovative approach to synthesise and study rare-earth magnetic materials. This achievement marks a significant advancement in understanding quantum magnetic states, potentially bringing the field closer to realising elusive quantum spin liquids.

Dr. Hyang-Tag Lim's research team at the Center for Quantum Technology at the Korea Institute of Science and Technology (KIST) has implemented a quantum computing algorithm that can estimate interatomic bond distances and ground state energies with chemical accuracy using fewer resources than conventional methods, and has succeeded in performing accurate calculations without the need for additional quantum error mitigation techniques.

A team led by Prof. LU Zhengtian and Researcher XIA Tian from the University of Science and Technology of China (USTC) realized Schrödinger-cat state with minute-scale lifetime using optically trapped cold atoms, significantly enhancing the sensitivity of quantum metrology measurement. The study was published in Nature Photonics.

Researchers at German carmaker Volkswagen Group and IQM Quantum Computers (IQM), say a hybrid approach of quantum and classical computing for battery simulation could help boost electric car batteries.

A new study published in Physical Review Letters on October 22 has challenged the assumptions by providing direct evidence of the breakdown of spin statistics in ion-atom charge exchange collisions. This study was led by scientists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS).
