Abstract
A technique relates to a microwave device. A qubit is connected to a first end of a first coupling capacitor and a first end of a second coupling capacitor. A resonator is connected to a second end of the first coupling capacitor and a second end of the second coupling capacitor. The resonator includes a fundamental resonance mode. A filter is connected to both the qubit and the first end of the first or second coupling capacitor.
