Fast high-fidelity gates for galvanically-coupled fluxonium qubits usingstrong flux modulation

HIGHLIGHTS

• who: Weiss D.K. from the DepartmentNorthwestern University, Evanston, Illinois, USA have published the paper: Fast High-Fidelity Gates for Galvanically-Coupled Fluxonium Qubits UsingStrong Flux Modulation, in the Journal: (JOURNAL) of 27/Dec/2022
• what: The authors show that the strength of this effective XX coupling changes sign as a function of the coupler flux and thus passes through zero. The authors describe how to execute two-qubit gates via parametric modulation of the coupler flux for a duration as short as a few drive periods. The authors show that identity gates can again . . .
