Enhancing quantum coherence of a fluxonium qubit by employing flux modulation with tunable-complex-amplitude

We propose to protect fluxonium qubits that are away from half flux quantum against environmental noises, especially 1 / f flux noise, by adopting a modulated flux with tunable-complex-amplitude. Using open-system Floquet theory, we derive a Lindblad equation and extract decoherent rates for pure-de...
