A newly identified quantum “miracle material” may enable magnetic switching, according to researchers from the University of Regensburg and the University of Michigan.
This discovery could lead to advancements in quantum computing, sensing, and other technologies. Previous studies found that quantum particles called excitons can sometimes be restricted to a single line within the material, chromium sulfide bromide. The new research provides both theoretical and experimental evidence linking this confinement to the material’s magnetic properties.
Chromium sulfide bromide is particularly exciting for quantum research because it can encode information in multiple ways: through electric charge, light (photons), magnetism (electron spins), and vibrations (phonons).
“The long-term vision is, you could potentially build quantum machines or devices that use these three or even all four of these properties: photons to transfer information, electrons to process information through their interactions, magnetism to store information, and phonons to modulate and transduce information to new frequencies,” said Mackillo Kira, U-M professor of electrical and computer engineering.
