Abstract
A method of multiplexing control lines of a qubit array includes applying a qubit control signal to a single driveline. The qubit control signal is split on the single driveline between a first resonator and a second resonator. The first driveline is operative to control a first qubit, a second tunable qubit, a third qubit, and a fourth tunable qubit. The first qubit is coupled to the second tunable qubit by the first resonator. The third qubit is coupled to the fourth tunable qubit by the second resonator. A variation in amplitude of the qubit control signal is compensated by adjusting a frequency of the second tunable qubit and a frequency of the fourth tunable qubit.
