Abstract
In a superconducting quantum processor, inductance is a characteristic of superconducting flux qubits and used to achieve coupling between qubits. In general, higher qubit energy scale results in better quantum processor performance. Energy scale of qubits can be increased by reducing inductance. For each Ising spin problem, qubit energy scale can be increased by determining the unused inductance-tuner range for each qubit and the minimum homogenized inductance achievable across all qubits, then adjusting the inductance-tuner to achieve the minimum homogenized inductance. When the inductance of a qubit is changed, there is a shift in the CCJJ bias at which quantum annealing is performed for that qubit. The variation in CCJJ bias shift can be compensated by computing the shift in CCJJ bias due to the applied inductance and applying a compensating CCJJ bias via the CCJJ offset DAC.
