A superconducting integrated circuit is fabricated by depositing a ground plane to at least partially overlie a substrate, depositing an insulating layer to at least partially overlie the ground plane, depositing a superconducting layer to at least partially overlie the insulating layer, and forming a superconducting feature in the superconducting layer. An inductance of the superconducting feature is tunable by adjusting a bias current in the ground plane. The ground plane is electrically communicatively coupleable to an electrical ground. Depositing a ground plane includes depositing a first superconducting material to at least partially overlie the substrate and depositing a second superconducting material to at least partially overlie the first superconducting material. A second critical current density of the second superconducting material is higher than a first critical current density of the first superconducting material.
