Physicists Measure Quantum Geometry for the First Time

2024-12-24

MIT physicists have, for the first time, measured the quantum geometry of electrons in solids. Using angle-resolved photoemission spectroscopy (ARPES), they overcame a long-standing challenge of directly measuring the geometry of quantum wave functions. This breakthrough opens new avenues for understanding and manipulating the quantum properties of materials, with potential applications in quantum computing and advanced electronics. The team's success involved international collaborations and innovative experimental design, navigating challenges posed by the COVID-19 pandemic.
