Quantum Devices Postdoctoral Fellow

Overview

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 Advanced Quantum Testbed (AQT) and Quantum System Accelerator (QSA) programs. The primary goal is to focus on materials and electric field engineering of circuits to improve coherence of superconducting qubits, including optimization of electromagnetic design and development of new fabrication techniques and metrology.

The position provides 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 role includes development and fabrication of a multiqubit, multilayer quantum processor unit (QPU), where Josephson junction engineering results will be implemented.

• Electromagnetic simulation of qubit circuits with novel designs to achieve high-coherence qubits.
• Fabrication process development and optimization to improve device materials and characterize the performance of superconducting qubit devices.
• Fabrication of multiqubit, multilayer quantum processor developed at Berkeley Lab.
• Improve the performance of superconducting devices, with emphasis on qubit lifetime and gate fidelity in multi-qubit devices.
• Present and publish experimental results in internal and external meetings and journals.
• Support and lead collaboration projects with quantum computing industrial partners.

• Mentoring graduate students.
• Support or lead writing including program reports, grants, and papers.

• 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:
  • 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 demonstrated 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 travel occasionally to collaborators’ sites and conferences.

• Experience in superconducting qubits
• Experience using Python-based programming tools
