Experience in superconductor logic families (e.g., RSFQ, ERSFQ, RQL, HFQ, AQFP). Experience performing tape-out of a superconducting IC chip. One or more published research paper or presentation at a relevant scientific conference. Preferred qualifications PhD in physics, electrical engineering, or a related engineering discipline. 7 years of research/industry experience in the design and simulation of superconductor digital logic circuits with 3 years of experience leading an R&D group towards tape-out and demonstration of superconducting IC chips. Experience with full digital design flow including RTL, synthesis, verification, timing closure, place-and-route, and post-fabrication validation. Experience with low-temperature measurements of superconductor digital logic circuits. Experience with superconducting qubits. Proficiency with computer-aided design tools and electromagnetic simulation tools. About the Job As a Research Scientist, your primary focus will be designing and simulating superconductor digital logic circuits (such as single flux quantum (SFQ) logic and adiabatic quantum flux parametron (AQFP) logic) for qubit control and readout. You will engage in co-design loops with qubit designers and superconducting digital circuit designers, utilizing advanced IC design tools, numerical circuit simulation techniques and 3D electromagnetic modeling to optimize signal integrity, minimize crosstalk, manage thermal budgets, and meet performance metrics required for coherent control of qubits. You will also interface with fabrication engineers to help define and establish IC design standards that are compatible for both the sensitive superconducting qubits and the co-located cryogenic control electronics, forming a fully integrated, modular chip stack that combines superconducting qubits with their control electronics directly within the cryogenic environment, accelerating the path toward large-scale, error-corrected quantum computing. Compensation US: $174000 - $253000 (USD) + 15% bonus target + equity + benefits. Responsibilities Design and simulate superconductor digital logic circuits (such as single flux quantum (SFQ) logic, adiabatic quantum flux parametron (AQFP) logic, and other emerging superconductor logic families) for generating waveforms tailored to qubit control and readout. Develop superconductor digital logic systems enabling multiplexed qubit control and readout. Address issues in the integration of superconductor digital electronics such as multi‑layer cell design, full‑chip clock synchronization, flux trapping, and signal integrity. Collaborate with teams focused on design, fabrication, and measurement to validate fully integrated quantum processors. Publish research papers and present at leading scientific conferences to advance and enhance publicity. Learn more about benefits at Google.
