Amplitude Spectroscopy of a Solid-State Artificial Atom
David M. Berns, Mark S. Rudner, Sergio O. Valenzuela +4
The energy-level structure of a quantum system plays a fundamental role in determining its behavior and manifests itself in a discrete absorption and emission spectrum. Conventiona…
Microwave-Induced Cooling of a Superconducting Qubit
S. O. Valenzuela, W. D. Oliver, D. M. Berns +3
We demonstrated microwave-induced cooling in a superconducting flux qubit. The thermal population in the first-excited state of the qubit is driven to a higher-excited state by way…
Coherent Quasiclassical Dynamics of a Persistent Current Qubit
D. M. Berns, W. D. Oliver, S. O. Valenzuela +4
A new regime of coherent quantum dynamics of a qubit is realized at low driving frequencies in the strong driving limit. Coherent transitions between qubit states occur via the Lan…
