In principle, a system that implements QEC can actually pass a \"break-even\" point and preserve quantum information for longer than the lifetime of its constituent parts. Reaching the break-even point, however, has thus far remained an outstanding and challenging goal. Several previous works have demonstrated elements of QEC in NMR, ions, nitrogen vacancy (NV) ce","authors_text":"Andrei Petrenko, Brian Vlastakis, Liang Jiang, Luigi Frunzio, Mazyar Mirrahimi, M. H.
