Measuring Quantum Temperatures: A New Thermometer for Quantumness and the Mystery of Quasicrystal Formation
Unlocking the Quantum Thermometer: A New Tool for Quantumness In a bold step for quantum science, researchers have developed a thermometer that doesn’t measure temperature in the classical sense but instead gauges the “quantumness” of a system. This innovative device aims to quantify how strongly a physical system behaves according to quantum rules, offering a…

Strain Engineering: Controlling Quantum Defects for Superior Performance
Strain Engineering Elevates Quantum Defects Researchers are pioneering a strain engineering framework that tunes how quantum defects behave in solid-state lattices, with the goal of enhancing spin readout contrast. Quantum defects—tiny imperfections in crystal lattices that trap individual electrons and their spins—are foundational to a range of quantum technologies, from ultra-sensitive sensors to emerging quantum…

Scientists Crack Loop Current Puzzle in Kagome Metals
What are kagome metals and why they matter Kagome metals are a select class of quantum materials whose atoms arrange in a distinctive basket-weave lattice. Named after the traditional Japanese kagome pattern, this geometry creates geometric frustration among electrons—an inability for them to settle into simple, periodic states. The result is a rich quantum landscape…

Kagome Metals Reveal Magnetic Switch of Loop Currents
Overview: A long-sought puzzle in quantum metals solved Researchers in Japan have provided the first comprehensive theoretical framework explaining how electricity behaves in kagome metals, a class of quantum materials with a distinctive basket-like lattice. The study shows that weak magnetic fields can reverse tiny loop electrical currents inside these metals, switching the material’s macroscopic…
