    Abstract: A method includes forming a capacitor pad (304A, 304B) for a nonlinear resonator. The method includes comparing a resonance frequency of the nonlinear resonator to a target frequency to determine whether the resonance frequency falls within a range of the target frequency. A device includes a first capacitor pad comprising a superconducting material, the first capacitor pad configured to couple to a first end of a logic circuit element. The device includes a second capacitor pad comprising a second superconducting material, the capacitor pad configured to couple to a second end of the logic circuit element. The second capacitor pad includes a first portion (306A, 306B); a second portion (308A, 308B); and a bridge (310A, 310B) configured to electrically connect the first portion (306A, 306B) and the second portion (308A, 308B).
