Observing super-quantum correlations across the exceptional point in a single, two-level trapped ion
Alexander Quinn, Jeremy Metzner, Jacob E. Muldoon +5
Quantum theory provides rules governing much of the microscopic world, and among its counter-intuitive consequences are correlations that exceed the bounds from local, classical th…
High-fidelity trapped-ion quantum logic using near-field microwaves
T. P. Harty, M. A. Sepiol, D. T. C. Allcock +3
We demonstrate a two-qubit logic gate driven by near-field microwaves in a room-temperature microfabricated ion trap. We measure a gate fidelity of 99.7(1)\%, which is above the mi…
Ion-trap electrode preparation with Ne bombardment
K. S. McKay, D. A. Hite, Y. Colombe +7
We describe an ex-situ surface-cleaning procedure that is shown to reduce motional heating from ion-trap electrodes. This precleaning treatment, to be implemented immediately befor…
High-fidelity preparation, gates, memory and readout of a trapped-ion quantum bit
T. P. Harty, D. T. C. Allcock, C. J. Ballance +5
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 i…
