Optimizing LZSM protocol for high-fidelity gates in open-system fluxonium
Santiago Ferreyra, Valentın Reparaz, Maria Jose Sanchez +2
Quantum gates based on resonant Rabi oscillations are inherently slow for small-frequency qubits. They are also prone to errors due to counter-rotating terms. However, when the anh…

Landau-Zener-Stückelberg spectroscopy of a fluxonium quantum circuit
ValentÃn Reparaz, MarÃa José Sánchez, Maximiliano Gatto +2
In this work, we study the time-averaged populations obtained for a fluxonium circuit under a large amplitude nonresonant periodic drive. We present numerical simulations of the ti…

Time-connected phase slips in current-driven two-band superconducting wires
Daniel Dominguez, Jorge Berger
We study quasi-one dimensional wires of two-band superconductors driven by an electrical current. We find that the onset of dissipation can occur with the nucleation of time-connec…
