Direct Wigner tomography of a superconducting anharmonic oscillator
Yoni Shalibo, Roy Resh, Ofer Fogel +4
The analysis of wave-packet dynamics may be greatly simplified when viewed in phase-space. While harmonic oscillators are often used as a convenient platform to study wave-packets,…
Sub-micrometer epitaxial Josephson junctions for quantum circuits
Jeffrey S. Kline, Michael R. Vissers, Fabio C. S. da Silva +11
We present a fabrication scheme and testing results for epitaxial sub-micrometer Josephson junctions. The junctions are made using a high-temperature (1170 K) "via process" yieldin…
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…
