Integrated information storage and transfer with a coherent magnetic device.

ABSTRACT: Quantum systems are inherently dissipation-less, making them excellent candidates even for classical information processing. We propose to use an array of large-spin quantum magnets for realizing a device which has two modes of operation: memory and data-bus. While the weakly interacting low-energy levels are used as memory to store classical information (bits), the high-energy levels strongly interact with neighboring magnets and mediate the spatial movement of information through quantum dynamics. Despite the fact that memory and data-bus require different features, which are usually prerogative of different physical systems--well isolation for the memory cells, and strong interactions for the transmission--our proposal avoids the notorious complexity of hybrid structures. The proposed m
