Optical quantum nondemolition measurement of a single rare earth ion qubit
Individually addressed rare earth atoms in solid crystals are an emerging platform for quantum information processing. Here the authors demonstrate a key requirement, by realizing single-shot, quantum non-demolition measurements of the spin of single Er3+ ions in Y2SiO5 crystals with nearly 95% fide...
