Quantum and Classical Chirps in an Anharmonic Oscillator
Yoni Shalibo, Ya'ara Rofe, Ido Barth +4
We measure the state dynamics of a tunable anharmonic quantum system, the Josephson phase circuit, under the excitation of a frequency-chirped drive. At small anharmonicity, the st…

Lifetime and Coherence of Two-Level Defects in a Josephson Junction
Yoni Shalibo, Ya'ara Rofe, David Shwa +4
We measure the lifetime () and coherence () of two-level defect states (TLSs) in the insulating barrier of a Josephson phase qubit and compare to the interaction stre…
