1. A resonator, comprising:
a coplanar waveguide (CPW) structure comprising;
a first end portion having a first width and configured to be coupled to a first qubit;
a middle portion having a second width that is narrower than the first width; and
a second end portion having a third width that is wider than the second width and configured to be coupled to a second qubit,
wherein an inductance of the middle portion is higher than an inductance of each of the first and second end portions.
