In a groundbreaking achievement for quantum technologies, researchers at the Cavendish Laboratory, University of Cambridge, have created a functional quantum register using the atoms inside a semiconductor quantum dot.

The rare-earth metal erbium could play a key role in future quantum networks: researchers from MPQ and TU Munich succeeded in spectrally resolving and individually controlling up to 360 erbium ions.

A €10m consortium funded by the European Commission and supported by the Quantum Flagship is using diamond and silicon carbide to build quantum computers and quantum simulators that can run at room temperature. The SPINUS project is developing quantum simulators with more than 50 qubits and quantum computers with over ten qubits, the team expects that their research will provide a strategy to scale up to over 1000 and 100 qubits, respectively, within five years post-project.

A new study has uncovered the universal dynamics far from equilibrium in randomly interacting spin models, thereby complementing the well-established universality in low-energy equilibrium physics. The study, recently published in Nature Physics, was the result of a collaborative effort involving the research group led by Prof. Du Jiangfeng and Prof. Peng Xinhua at the University of Science and Technology of China (USTC), along with the theoretical groups of Prof. Zhai Hui from Tsinghua University and Dr. Zhang Pengfei from Fudan University.

The strength of a coupling between nuclear spins depends on chirality, or handedness, of the molecule, according to a new study by researchers at UCLA, Arizona State University, Penn State, MIT and Technische Universität Dresden. The study also revealed that in chiral molecules of a given handedness – whether it is a left- or right-handed molecule – the nuclear spin tends to align in one specific direction. In molecules with the opposite chirality, such as right-handedness, the spin aligns in the opposite direction.

Researchers from Delft University of Technology in The Netherlands have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom. This electron could be manipulated and read out through the needle of a scanning tunneling microscope.

Dynamic nuclear polarization (DNP) has revolutionized the field of nanoscale nuclear magnetic resonance (NMR), making it possible to study a wider range of materials, biomolecules and complex dynamic processes such as how proteins fold and change shape inside a cell.

A research team led by Prof PENG Xinhua and Associate Prof. JIANG Min from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has discovered the Fano resonance interference effect between mixed atomic spins. They proposed a novel magnetic noise suppression technique, reducing magnetic noise interference by at least two orders of magnitude. The study was published in Physical Review Letters.

Researchers at Mainz University and the University of California, Berkeley, achieve a breakthrough in zero-field nuclear magnetic resonance spectroscopy, paving the way towards benchmarking quantum chemistry calculations.
