Single ion qubit with estimated coherence time exceeding one hour

Single ion qubit with estimated coherence time exceeding one hour

Extending qubit coherence times represent one of the key challenges for quantum technologies. Here, after properly suppressing magnetic-field fluctuations, frequency instability and leakage of the microwave reference-oscillator, the authors infer coherence times of 5500 s for an Yb ion qubit.
