Time-optimal quantum gates with bang-bang control in multilevel systems
Valentín Reparaz, Santiago Ferreyra, María José Sánchez +2
We determine the optimal quantum manipulation protocols for implementing high-fidelity, fast single-qubit gates. We demonstrate that the time-optimal pulse sequence is a ``bang-ban…

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…

Fast quantum gates based on Landau-Zener-Stückelberg-Majorana transitions
Joan J. Caceres, Daniel Dominguez, Maria Jose Sanchez
Fast quantum gates are of paramount importance for enabling efficient and error-resilient quantum computations. In the present work we analyze Landau-Zener-Stückelberg-Majorana (LS…
