More generally, our combined analytical and numerical strategy allows us to characterize two-qubit gates involving parametrically driven interactions, and can be applied to gate optimization and cross-talk mitigation such as the cancellation of unwanted ZZ interactions in multi-qubit architectures. Here, we demonstrate an improvement of up to a factor of 3 in algorithmic performance as measured by the success probability, by implementing a continuous hardware-efficient gate set using superconducting quantum circuits. Finally, we measure lifetimes of several excited states ranging from T1=620 ns to T1=20 μs, by applying consecutive π-pulses between multiple fluxonium levels. C. Lang, C. Eichler, L. Steffen, J. M.

By analogy with Cavity Quantum Electrodynamics (CQED), circuit QED (cQED) exploits the fact that a simple model can be used to both describe the interaction of an atom with an optical cavity and a qubit with a microwave resonator. Our analytical treatment, based on time-dependent Schrieffer-Wolff perturbation theory, yields closed-form expressions for gate frequencies and spurious interactions, and is valid for strong drives. We find that the parity symmetry of the qubit results in charge-insensitive levels connecting the protected states, allowing for logical operations. Ong, P. Bertet, D. Vion, D. Esteve and A. Blais.
