Increasing the energy scale of a quantum processor improves its performance. Energy scale of a quantum processor may be increased by increasing the coupling strength of communicatively coupled superconducting devices comprised in the quantum processor. Configuring the physical dimensions of communicatively coupled superconducting devices such that an intentional direct coupling is induced between a pair of superconducting devices communicatively coupled by a coupling device may controllably add an additional mutual inductance to the mutual inductance of the pair of superconducting devices. Furthermore, reducing the beta parameter of a coupling device may improve the tunability of the coupling device. The combined effects of improved tunability of the coupling devices and the increased coupling strength between superconducting devices communicatively coupled by respective coupling devices comprised in the quantum processor may thus improve the performance of the quantum processor.
