Abstract
Time-dependent eigenstates of Hamiltonians offer a large degree of tunability, which can be leveraged to operate single- and two-qubit gates so that they stay dynamically protected from noise. However, the usual analytical techniques for describing these gates are limited for systems subject to drives of different frequencies. Thus the authors generalize the Floquet approach to the understanding of such systems, and provide protocols to robustly control and measure these complex systems.
