Quantum Devices Postdoctoral Fellow

Lawrence Berkeley National Laboratory • Berkeley, CA

69d • Hybrid

About The Position

Berkeley Lab’s Applied Mathematics Computational Research Division (AMCR) has an immediate opening in the Quantum Information Science and Technology Group (QuIST) for a Quantum Devices Postdoctoral Fellow under the programs of Advanced Quantum Testbed (AQT) and Quantum System Accelerator (QSA). The primary goal of the position will focus on materials and electric field engineering of circuits to improve the coherence of superconducting qubits, including the optimization of electromagnetic design and development of new fabrication techniques and metrology. The position will have access to the state-of-the-art superconducting circuit fabrication facility, quantum measurement lab, and advanced material characterization tools at Lawrence Berkeley National Laboratory. The position will also be on the team for development and fabrication of multiqubit, multilayer quantum processor unit (QPU), where the result of Josephson junction engineering will be implemented.
We are looking for:

Requirements

• Ph.D. degree in Physics, Applied Physics, Electrical Engineering, or a related field.
• Experience in Cleanroom/nanofabrication processes, preferably in e-beam lithography, thin-film deposition, and plasma etching.
• Knowledge of quantum information science related to one or more of the responsibilities/research areas in the following:
• Quantum computing
• Microwave circuit simulation (e.g. EM solvers, network analysis) and design (circuit routing and mask layout, .gds, .dxf, etc.)
• Microwave or cryogenic measurement
• Relevant publication record and demonstration of proficient written and verbal presentation of scientific results.
• Ability to work effectively in a collaborative environment.
• Ability to mentor and direct the work of students.
• Willingness to occasional traveling to collaborators’ sites and conferences.

Nice To Haves

• Mentoring graduate students.
