Researchers at the University of Chicago and Argonne National Lab have developed a new type of optical memory that stores data by transferring light from rare-earth element atoms embedded in a solid material to nearby quantum defects. Current optical storage has a hard cap on data density because each single bit can't be smaller than the wavelength of the reading/writing laser. One of the fundamental discoveries was that when a defect absorbs the narrow wavelength energy from those nearby atoms, it doesn't just get excited – its spin state flips.
