SYSTEMS AND METHODS FOR FABRICATING SUPERCONDUCTING INTEGRATED CIRCUITS

Systems and methods for fabricating a superconducting integrated circuit that includes wiring layers comprising low-noise material are described. A superconducting integrated circuit can be implemented in a computing system that includes a quantum processor. Such a superconducting integrated circuit includes a first set of one or more wiring layers that form a noise-susceptible superconducting device that can decrease processor when exposed to noise. The superconducting integrated circuit can further include a second set of one or more wiring layers that form a superconducting device that is less susceptible to noise. Fabricating a superconducting device that contains low-noise material can include depositing and patterning a wiring layer comprising a first material that is superconductive in a respective range of temperatures and depositing and patterning a different wiring layer comprising a second material that is superconductive in a respective range of temperatures. The second material can be considered a low-noise material.
