Long-lived metastable-qubit memory
The authors demonstrate an experimental realization of a long-lived quantum memory using the optical-frequency--metastable-state--ground-state architecture in a trapped ion, where the qubit is stored in the metastable states while an ancillary ion is used for sympathetic cooling. A dynamical decoupling sequence and leakage detection are employed to extend the coherence time to approximately four times the natural lifetime of the metastable state.
