Chaining atoms together yields quantum storage

Journal Reference: Andrei Ruskuc, Chun-Ju Wu, Jake Rochman, Joonhee Choi, Andrei Faraon. Nuclear spin-wave quantum register for a solid-state qubit. Nature, 2022; 602 (7897): 408 DOI: 10.1038/s41586-021-04293-6 The new system relies on nuclear spins — the angular momentum of an atom’s nucleus — oscillating collectively as a spin wave. This collective oscillation effectively chains up … Read more
