Drive-induced nonlinearities of cavity modes coupled to a transmon ancilla
Drive-induced nonlinearities of cavity modes coupled to a transmon ancilla
When microwave cavity modes and transmon qubits are coupled, the cavity modes inherit nonlinearity from the transmons. Here, the authors investigate how a driving field affects this nonlinearity, comparing analytical, numerical, and experimental results. They show that an off-resonant driving field can even be used to cancel the dominant nonlinearity, …
