Título: | Large-amplitude driving of a superconducting artificial atom |
Otros títulos: | Interferometry, cooling, and amplitude spectroscopy | Autor: | Oliver, William D.; Valenzuela, Sergio O. CSIC ORCID | Fecha de publicación: | 2009 | Editor: | Springer Nature | Citación: | Quantum Information Processing 8(2-3): 261-281 (2009) | Resumen: | Superconducting persistent-current qubits are quantum-coherent artificial atoms with multiple, tunable energy levels. In the presence of large-amplitude harmonic excitation, the qubit state can be driven through one or more of the constituent energy-level avoided crossings. The resulting Landau-Zener- Stückelberg (LZS) transitions mediate a rich array of quantum-coherent phenomena. We review here three experimental works based on LZS transitions: Mach-Zehnder-type interferometry between repeated LZS transitions, microwave-induced cooling, and amplitude spectroscopy. These experiments exhibit a remarkable agreement with theory, and are extensible to other solid-state and atomic qubit modalities. We anticipate they will find application to qubit state-preparation and control methods for quantum information science and technology. © 2009 Springer Science+Business Media, LLC. | Descripción: | arXiv:0906.0185v1 | Versión del editor: | http://dx.doi.org/10.1007/s11128-009-0108-y | URI: | http://hdl.handle.net/10261/122537 | DOI: | 10.1007/s11128-009-0108-y | Identificadores: | doi: 10.1007/s11128-009-0108-y issn: 1570-0755 e-issn: 1573-1332 |
