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.

The Korea Research Institute of Standards and Science (KRISS) has, for the first time in the world, generated and controlled skyrmions at room temperature in a two-dimensional (2D) materials. This achievement reduces power consumption compared to traditional three-dimensional (3D) systems while maximizing quantum effects, making it a core technology for the development of room-temperature quantum computers and AI semiconductors.

Quantum technologies exploit the unusual properties of the most fundamental building blocks of matter. They promise breakthroughs in communication, computing, sensors and much more. However, quantum states are fragile, and their effects are difficult to grasp, making research into real-world applications challenging. Empa researchers and their partners have now achieved a breakthrough: Using a kind of “quantum Lego”, they have been able to accurately realize a well-known theoretical quantum physics model in a synthetic material.

Irish-headquartered Equal1 expands team to include renowned scientists from TNO, the Netherlands Organisation for Applied Scientific Research.

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).

RRI which developed the technology for precision laser systems required for quantum enabled-technology applications and industrial uses, recently awarded the license to nexAtom Research and Instruments, the first spin-off company from RRI. This spinoff company will soon commence production of the multi-channel, tunable laser system technology platforms. RRI has filed a provisional Indian patent for ‘Standalone laser system with frequency tunability and precision control’.

Peter Fischer, a senior researcher at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), led a project to make 3D X-ray images of skyrmions that can characterize or measure the orientations of spins inside the whole object. “Our results provide a foundation for nanoscale metrology for spintronics devices,” Fischer said. The work was recently published in Science Advances.

The University of Basel and QuantumBasel have agreed to collaborate to further develop the Center for Quantum Computing and Quantum Coherence (QC2) at the Department of Physics into a leading center of excellence for quantum computing and to strengthen the bridge between cutting-edge research and industrial applications in quantum computing. This partnership will enhance the cluster of quantum research in the Basel region and drive the development of quantum algorithms and their practical application. This will strengthen Switzerland's position in the international race for the leading role in technology.

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.

A research team led by Academician Guo Guangcan, Prof. GUO Guoping and Prof. LI Haiou from the University of Science and Technology of China (USTC), collaborating with Researcher ZHANG Jianjun from the Institute of Physics of the Chinese Academy of Sciences (CAS) achieved coherent population trapping (CPT) in a semiconductor double quantum dot (DQD) system. Their work was published in Nano Letters.
