Abstract
Systems and methods for balanced inductive and capacitive coupling for quantum circuits are provided. A quantum circuit can include a qubit structure comprising an inductor and at least a first portion of a qubit capacitor. The quantum circuit can further include a ground, and a second portion of the qubit capacitor coupled to the ground. The quantum circuit can further include a readout resonator configured to measure a state of the qubit structure. The quantum circuit can further include a capacitive coupling between the readout resonator and the qubit structure and an inductive coupling between the readout resonator and the inductor of the qubit structure. A coupling strength of the inductive coupling and a coupling strength of the capacitive coupling can be approximately equal in magnitude.
