What are the responsibilities and job description for the Quantum Devices Postdoctoral Fellow position at Berkeley Lab?
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.
