Breakdown of the escape dynamics in Josephson junctions
D. Massarotti, D. Stornaiuolo, P. Lucignano +7
We have identified anomalous behavior of the escape rate out of the zero-voltage state in Josephson junctions with a high critical current density Jc. For this study we have employ…
Resolving the effects of frequency dependent damping and quantum phase diffusion in YBaCuO Josephson junctions
D. Stornaiuolo, G. Rotoli, D. Massarotti +4
We report on the study of the phase dynamics of high critical temperature superconductor Josephson junctions. We realized YBaCuO (YBCO) grain boundary (GB) biepitax…
Direct transition from quantum escape to phase diffusion regime in YBaCuO biepitaxial Josephson Junctions
Luigi Longobardi, Davide Massarotti, Daniela Stornaiuolo +4
Dissipation encodes interaction of a quantum system with the environment and regulates the activation regimes of a Brownian particle. We have engineered grain boundary biepitaxial…
Microstrip filters for measurement and control of superconducting qubits
Luigi Longobardi, Douglas A. Bennett, Vijay Patel +2
Careful filtering is necessary for observations of quantum phenomena in superconducting circuits at low temperatures. Measurements of coherence between quantum states requires exte…
High critical-current density and scaling of phase-slip processes in YBaCuO nanowires
G. Papari, F. Carillo, D. Stornaiuolo +3
YBaCuO nanowires were reproducibly fabricated down to widths of 50 nm. A Au/Ti cap layer on YBCO yielded high electrical performance up to temperatures above 80 K in single nanowir…
Quantum crossover in moderately damped epitaxial NbN/MgO/NbN junctions with low critical current density
Luigi Longobardi, Davide Massarotti, Giacomo Rotoli +6
High quality epitaxial NbN/MgO/NbN Josephson junctions have been realized with MgO barriers up to a thickness of d=1 nm. The junction properties coherently scale with the size of b…
