Scalable simultaneous multiqubit readout with 99.99% single-shot fidelity
We describe single-shot readout of a trapped-ion multiqubit register using space- and time-resolved camera detection. For a single qubit we measure 0.9(3)×10-4 readout error in 400μs exposure time, limited by the qubit's decay lifetime. For a four-qubit register (a "qunybble"), we mea...
