Title: QUBIT DEVICES WITH SLOW WAVE RESONATORS
Abstract:
Embodiments of the present disclosure propose new microwave resonator structures for providing microwave connectivity to, from, and/or between qubits, or to set the frequencies that address individual qubits. An exemplary proposed resonator structure includes a resonant microwave transmission line having periodic high-impedance and low-impedance sections along at least a portion of the entire length of the line. In some embodiments, such sections can be implemented by providing periodic conductive elements which are substantially perpendicular to a signal line of a microwave transmission line. In various embodiments, the periodic conductive elements may be provided either in the same plane as the signal line, or in a plane below the signal line and separated from the signal line by a dielectric material. Fabrication techniques for forming such resonators are also disclosed.
