Light reads electron spins inside porous crystals, opening path to quantum chemical sensors

AI Summary

An international research team has used light to detect the magnetic spin of electrons trapped within a porous metal-organic framework crystal. The technique could support the development of a new generation of quantum chemical sensors.

University of Glasgow researchers are part of an international collaboration that could lead to a new generation of quantum sensors. The team, which included researchers from the University of Tokyo, University of Glasgow, University of Sheffield and Kobe University, has for the first time used light to read out the magnetic spin of electrons trapped inside a porous crystalline material known as a metal-organic framework (MOF).
