講演概要
In this talk, we present recent work on fluxonium single- and two-qubit gates with high fidelity [1,2]. In the case of single-qubit gates, we go beyond restrictions associated with the rotating-wave approximation by accounting for the carrier-envelope phase drive and fixing it through pulse timing. The timing aspect is closely related to our earlier work on universal nonadiabatic baseband control of composite (dual-rail) qubits [3].
