Abstract:

With a 9Be trapped-ion hyperfine-states qubit, we demonstrate an error probability per randomized single-qubit gate of 2.02 x 10-5 below the threshold estimate of 10-4 commonly considered sufficient for faulttolerant quantum computing. The 9Be ion is trapped above a microfabricated surface-electrode ion trap and is manipulated with microwaves applied to a trap electrode. The achievement of low single-qubit-gate errors is an essential step toward the construction of a scalable quantum computer.
