About the Cover

Artist’s (Peter Allen) conception of individual nuclear spin memories, where information encoded within the circling electron spins is coherently transferred into the subatomic core of the nearby atoms. Fabricated in single crystal diamond films, these single nuclear spin storage devices operate within a hundred nanoseconds and suggest pathways to develop systems with unprecedented storage densities.
