Classification: CPC G  H | IPC G  H

Claim 12:
13. A multi-qubit chip formed by:
forming a plurality of qubits on a chip, wherein each qubit comprises a Josephson junction and a capacitor connected in parallel with one another;
measuring a resonance frequency of each qubit on the chip;
determining a set-point frequency for each qubit that achieves a defined collision probability with respect to a probability of frequency collisions between adjacent qubits; and
annealing a first Josephson junction of a first qubit of the plurality of qubits, based on parameters for the annealing from a database that relates the parameters to frequency shifts, to modify the resonance frequency of the first qubit from a first resonance frequency to about a first set-point frequency determined for the first qubit; and
annealing a second Josephson junction of a second qubit of the plurality of qubits, based on the parameters from the database, to modify the resonance frequency of the second qubit from a second resonance frequency to about a second set-point frequency determined for the second qubit, wherein the first set-point frequency is different than the second set-point frequency.
