High-Fidelity Preparation, Gates, Memory, and Readout of a Trapped-Ion Quantum Bit.
We implement all single-qubit operations with fidelities significantly above the minimum threshold required for fault-tolerant quantum computing, using a trapped-ion qubit stored in hyperfine "atomic clock" states of ^{43}Ca^{+}. We measure a combined qubit state preparation and single-sho...
