Jeffrey S. Birenbaum

Dr. Jeffrey S. Birenbaum is a technical staff member in the Quantum Information and Integrated Nanosystems Group. He works primarily on cryogenic operation of complementary metal-oxide-semiconductor (CMOS) technology. His current research is focused on the performance tradeoffs of conventional CMOS circuits down to 4 K, and the reliability of CMOS circuits and supporting infrastructure, including packaging and measurement components, in cryogenic applications.

Birenbaum joined Lincoln Laboratory after completing his doctoral studies at the University of California, Berkeley with his advisor, Dr. John Clarke. His graduate work focused on the study and reduction of intrinsic 1/f flux noise in superconducting quantum interference devices (SQUIDs) and superconducting qubits. His thesis, The C-Shunt Flux Qubit: A New Generation of Superconducting Flux Qubit, explores the design, fabrication, and measurement of capacitively-shunted superconducting flux qubits.

Birenbaum has coauthored six peer-reviewed papers and has given presentations at conferences across the country in the field of superconducting qubits and flux noise.

Birenbaum received his PhD degree in physics from the University of California, Berkeley and his BS degree in physics and math from the University of Maryland.
