Disclosed herein are superconducting qubit devices with Josephson Junctions utilizing resistive switching materials, i.e., resistive Josephson Junctions (RJJs), as well as related methods and quantum circuit assemblies. In some embodiments, an RJJ may include a bottom electrode, a top electrode, and a resistive switching layer (RSL) disposed between the bottom electrode and the top electrode. Using the RSLs in Josephson Junctions of superconducting qubits may allow fine tuning of junction resistance, which is particularly advantageous for optimizing performance of superconducting qubit devices. In addition, RJJs may be fabricated using methods that could be efficiently used in large-scale manufacturing, providing a substantial improvement with respect to approaches for forming conventional Josephson Junctions, such as e.g. double-angle shadow evaporation approach. |
