Fabrication Control of Superconducting Qubit Devices
· Invited
Abstract
Superconducting qubits with Josephson junction elements are gaining traction as a key modality towards the realization of a quantum computer. These devices have transitioned from scientific discovery to device optimization as the materials, fabrication processes, designs, and measurement capabilities are maturing. Precise control of junction parameters is needed for ideal device performance, especially as system sizes and complexity grow. Motivated by device coherence times, I will discuss our work to understand and control the uniformity of Josephson junctions in the size range best suited for device performance.
