The spin lifetime of an individual atomic nucleus investigated via local-probe single-shot readout

Kavli Affiliate: Sander Otte | First 5 Authors: Evert W. Stolte, Jinwon Lee, Hester Vennema, Rik Broekhoven, Esther Teng | Summary: Nuclear spins owe their long-lived magnetic states to their excellent isolation from their environment. At the same time, a limited degree of interaction with their surroundings is necessary for reading and writing the spin […]
