Moiré superlattices, structures that arise when two layers of two-dimensional (2D) materials are overlaid with a small twist angle, have been the focus of numerous physics studies. This is because they have recently been found to host novel fascinating unobserved physical phenomena and exotic phases of matter.

Researchers in the Institute for Molecular Science revealed the quantum entanglement between electronic and motional states in their “ultrafast quantum simulator,” generated by the repulsive force due to the strong interaction between Rydberg atoms. They also propose a new quantum simulation method including repulsive force between particles. This achievement is published August 30th in Physical Review Letters.

Researchers from the National University of Singapore (NUS) have successfully simulated higher-order topological (HOT) lattices with unprecedented accuracy using digital quantum computers. These complex lattice structures can help us understand advanced quantum materials with robust quantum states that are highly sought after in various technological applications.

Researchers created a new entangled quantum state of matter by building an artificial quantum material atom-by-atom. The state, dubbed a higher-order topological quantum magnet, may be a way to address key problems in quantum technology, such as decoherence in qubits.

A research traineeship program developed by a team of Rice University faculty led by Junichiro Kono has received an award of $3 million over five years from the National Science Foundation (NSF) to equip a new generation of scientists and engineers with the skills needed to serve as leaders in quantum technology innovation.

In a study titled „Near-complete chiral selection in rotational quantum states" published in Nature Communications, the Controlled Molecules Group from the Molecular Physics Department of the Fritz Haber Institute has made a significant leap forward in the field of chiral molecules. The team, led by Dr. Sandra Eibenberger-Arias, achieved near-complete separation in quantum states for these essential components of life.

A recent study led by University of Minnesota Twin Cities researchers provides fundamental insight into how light, electrons, and crystal vibrations interact in materials. The research has implications for developing on-chip architectures for quantum information processing, significantly reducing fabrication constraints, and thermal management.

Researchers have now demonstrated that the nonlinear optical response is unprecedently strong in a two-dimensional device made of three atomic layers of the semiconductor tungsten di-selenide (WSe2). The researchers also showed that the giant nonlinear response can be tuned.

Cornell University researchers have demonstrated that acoustic sound waves can be used to control the motion of an electron as it orbits a lattice defect in a diamond, a technique that can potentially improve the sensitivity of quantum sensors and be used in other quantum devices.

A study coordinated by the University of Trento with the University of Chicago proposes a generalized approach to treat the interactions between electrons and light. In the future, it may contribute to the development of quantum technologies but also to the discovery of newstates of matter. The study has been published in Physics Review Letters.
