Compact Resonator with Shifted Higher Modes for Quantum Buses

Abstract:

A resonator is based on a coplanar waveguide (CPW) structure that includes a first end portion having a first width and configured to be coupled to a first qubit. There is a a middle portion having a second width that is narrower than the first width. There is a second end portion having a third width that is wider than the second width and configured to be coupled to a second qubit.
