Quantum Engineering Postdoctoral Fellow

About the role

The Quantum Engineering Postdoctoral Fellow will focus on materials and circuit electric field engineering to understand the material-performance causality of superconducting qubits, including the optimization of electromagnetic design and development of new metrology and fabrication techniques. Access to state-of-the-art facilities at Lawrence Berkeley National Laboratory includes a superconducting circuit fabrication facility, quantum measurement lab, and advanced material characterization tools.

Responsibilities

• Perform electromagnetic simulation of qubit circuits with novel designs to achieve high coherence qubits.
• Develop cleanroom metrology for superconducting qubit devices, especially CMOS in-line metrology, in lab as well as in collaboration with industrial partners.
• Fabricate process development and optimization to improve device materials and characterize the performance of superconducting qubit devices.
• Develop and fabricate multiqubit, multilayer quantum processor unit (QPU).
• Present and publish experiment results in internal and external meetings and journals.
• Support and lead collaboration projects with quantum computing industrial partners.

Requirements

• Ph.D. degree in Physics, Applied Physics, Electrical Engineering, Material Science, or a related field.
• Experience in cleanroom/nanofabrication processes, with an emphasis on the hands-on experience and knowledge on cleanroom metrology for device performance/yield characterization.
• Experience in solid state quantum computing platform, including but not limited to: superconducting qubits, spin qubit, semiconductor nanowire/topological qubits, rare-earth qubit, nanophotonic.
• Experience with microwave circuit design and simulation (e.g. EM solvers, network analysis).
• Experience with complex structure device fabrication, including CMOS multilayer devices, flip-chip devices, microwave airbridges, and/or RF circuit devices.
• 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.

Qualifications

• Desired skills/knowledge include experience in superconducting qubits design, fabrication, and measurement, especially in surface participation simulation and material loss tangent.
• Familiarity with material-device causality, i.e., connecting film microstructure, surface chemistry, to device physics and performance.
• Experience with surface treatment and surface metrology/measurement.

Benefits

• Exceptional health and retirement benefits, including pension or 401K-style plans.
• Opportunities to grow in your career through the Tuition Assistance Program.
• A culture where you'll belong - we are invested in our teams!
