Analytical multi-level LZSM optimization plus Floquet-Born-Markov open-system fidelity shows fluxonium Y(π/2) gates under 1.3 ns with error below 10^{-5} at privileged drive frequencies.
A Fourier-engineered cos(2φ) qubit achieves spectral agreement with theory but its energy relaxation is limited by 1/f flux noise from residual first-harmonic fluctuations, unlike similar fluxonium qubits.
Lighter fluxonium qubits show lower susceptibility to measurement-induced state transitions than heavier counterparts due to reduced multi-photon resonance density, smaller required coupling, and more harmonic charge operator structure.
A floating tunable coupler allows 24 ns adiabatic CZ gates above 99.9% fidelity with exact ZZ=0 at idle for fixed-frequency transmons.
A system-level design methodology for scalable fluxonium processors with double-transmon couplers that supports high-fidelity gates, fast reset, and dispersive readout through frequency partitioning under realistic constraints.
