In superconducting quantum processors, the predictability of device parameters is of increasing importance as many laboratories scale up their systems to larger sizes in a 3-D-integrated architecture.In particular, the properties of superconducting resonators must be controlled well to ensure high-fidelity multiplexed readout of qubits.Here, we present a method, based on conformal mapping techniques, to predict a resonator's parameters directly from wac 4011 its 2-D cross-section, without computationally heavy and time-consuming 3-D simulation.

We demonstrate the method's validity by comparing the calculated incredibleindiatourtravels.com resonator frequency and coupling quality factor with those obtained through 3-D finite-element-method simulation and by measurement of 15 resonators in a flip-chip-integrated architecture.We achieve a discrepancy of less than 2% between designed and measured frequencies for 6-GHz resonators.We also propose a design method that reduces the sensitivity of the resonant frequency to variations in the interchip spacing.
