Quantum Compute Nanofabrication Engineer

The role, as Western Digital Technologies, Inc. describes it

We are seeking a talented researcher to join our team and drive innovative research projects in quantum computing, specifically to focus on quantum compute devices nanofabrication. The key emphasis of the project will be design and nanofabrication of superconducting qubit and QPU test devices, intended for thorough understanding of the links between nanofabrication choices and devices performance, as applied to both flux tunable and fixed frequency qubits nanofabricated in various Al, Nb and Ta-based superconducting qubit systems. The overarching goal of the project is to translate exceptional process uniformity abilities in Western Digital into exceptional resonator and qubit performance uniformity across the wafer, and from wafer to wafer. In the course of the project, you will collaborate with both room temperature and low temperature DC and RF metrology scientists to accurately measure and monitor realistic population lifetime distributions, and materials scientist working on wafer level characterization, and drive feedback to our quantum device design and implement nanofabrication process. Successful candidates are expected to have deep familiarity with superconducting qubit design, and variety of nanofabrication techniques typically applied to superconducting qubit devices, such as optical and e-beam lithography, reactive ion etching, chemically assisted ion beam etching, atomic layer etching, physical vapor deposition, chemical vapor deposition, ion beam deposition and other.
