SAFE uses a weak off-resonant drive on a flux-tunable transmon to create a dynamical sweet spot where cavity frequency fluctuations from flux noise are cancelled, extending simulated cavity dephasing times by over an order of magnitude.
This yields the Floquet eigenvalue equation H(t)−i∂ t |ψn(t)⟩=ε n|ψn(t)⟩.(A2) Since the quantities on both sides of Eq
