Control of Transverse Motion for Quantum Gates on Individually Addressed Atomic Qubits

Open access

Abstract

Individual trapped atomic qubits represent one of the most promising technologies to scale quantum computers, owing to their low idle errors and the ability to implement a full set of reconfigurable gate operations via focused optical fields.However, the fidelity of quantum gate operations can be limited by weak confinement of the atoms transverse to the laser.We present measurements of this effect by performing individually addressed entangling gates in chains of up to 25 trapped atomic ions.We present a semiclassical model that accurately describes the observed decoherence from the residual heating of the ions caused by noisy electric fields.We suppress these effects by cotrapping ancilla ions for sympathetically cooling the qubit ions throughout a quantum circuit.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
