Harnessing many-body spin environment for long coherence storage and high-fidelity single-shot qubit readout
Hybrid quantum devices based on coupled nuclear and electron spins offer promising applications, but require long nuclear spin coherence times. Here the authors demonstrate millisecond coherence times for a nuclear spin ensemble coupled to a single electron spin qubit in a semiconductor quantum dot.
