Error Budget for the Sørensen-Mølmer Gate — •Susanna Kirchhoff1,2, Frank Wilhelm-Mauch1,2, and Felix Motzoi3 — 1Institute of Quantum Computing Analytics (PGI 12), Forschungszentrum Jülich, Germany — 2Theoretical Physics, Saarland University, Saarbrücken, Germany — 3Institute of Quantum Control (PGI-8), Forschungszentrum Jülich, Germany
The Sørensen-Mølmer gate is an entangling gate for ion qubits, where the entanglement is achieved by a bichromatic laser beam. The gate speed and fidelity are limited by leakage to other levels. We present a detailed expression for the fidelity including higher Lamb-Dicke orders and propose methods to improve gate speed and fidelity.
