Optical control of nuclear spins in molecules points to new paths for quantum technologies

Researchers at the Karlsruhe Institute of Technology (KIT) have reported important progress in quantum physics and materials science by optically initializing, controlling, and reading out nuclear spin states in a molecular material for the first time. Because of their weak interaction with the environment, nuclear spins are particularly stable quantum information carriers. The research, published in Nature Materials, shows that molecular nuclear spins could be a promising building block for future quantum technologies.
