Systems and methods for increasing the energy scale of a quantum processor

A method of operation of a quantum processor, wherein the quantum processor includes a first superconducting device comprising having a respective loop of material that is superconductive at or below threshold temperatures and at least one respective Josephson junction that interrupts the respective loop, a second superconducting device comprising having a respective loop of material that is superconductive at or below threshold temperatures and at least one respective Josephson junction that interrupts the respective loop, where the respective loops of the first and the second superconducting devices partially overlap one another and are not electrically contiguous with one another, a first portion of the respective loop of at least the first superconducting device arranged perpendicularly with respect to a first portion of the respective loop of the second superconducting device and a second portion of the respective loop of at least the first superconducting device arranged non-perpendicularly with respect to a second portion of the respective loop of the second superconducting device to directly communicatively couple the first superconducting device and the second superconducting device without any intervening superconducting devices, and a superconducting coupler operable to indirectly communicatively couple the first and the second superconducting devices to one another, the method comprising:

• adjusting a beta value of the superconducting coupler that indirectly communicatively couples the first superconducting device and the second superconducting device based at least in part on the non-perpendicular orientation of the second portion of the first superconducting device with respect to the second portion of the second superconducting device which are also directly communicatively coupled without any intervening superconducting devices or superconducting couplers;
• and
• communicatively coupling a signal to at least one of the first superconducting device or the second superconducting device.
