Classification: CPC G  H | IPC G  H

Claim 17:
18. A multi-qubit chip formed by:
determining a set-point frequency for each qubit of a plurality of qubits on the multi-qubit chip that achieves a defined collision probability with respect to a probability of frequency collisions between adjacent qubits;
based on the set-point frequency for each qubit, forming the plurality of qubits on the multi-qubit chip, wherein each qubit comprises a Josephson junction and a capacitor connected in parallel with one another;
measuring a first frequency of a first qubit of the plurality of qubits; and
annealing the Josephson junction of the first qubit, based on parameters for the annealing from a database that relates the parameters to frequency shifts, to adjust the frequency of the first qubit from the first frequency to about a first set-point frequency determined for the first qubit.
