Job Opportunity: Research Associate Position, Boulder Cryogenic Quantum Testbed

 LOCATION: NIST (Boulder, Colorado), Quantum Sensors Division (687), Quantum Electronics Group (14)

The Quantum Sensors Division of NIST located in Boulder Colorado is currently seeking a full-time research associate in experimental superconducting quantum computing to work on the Boulder Cryogenic Quantum Testbed project1. The Boulder Cryogenic Quantum Testbed aims to improve the accuracy, precision, and reproducibility of performance measurements of superconducting microwave resonators, especially for materials loss investigations and ultralow powers and millikelvin temperatures. The goals of this work include the study of asymmetric resonance fitting, cryogenic calibration, high-throughput measurement techniques, probing of two-level systems, understanding quasiparticle effects, and resonator device design, among others.

SUMMARY OF THE POSITION: The research associate will support the development of methods to improve the accuracy, precision, and reproducibility of performance measurements of superconducting microwave resonators at ultralow powers and millikelvin temperatures. The research associate will guide the bring-up of a new high-throughput cryogenic microwave measurement system for superconducting microwave resonator dielectric loss, including wiring installation and completing automation of device identification, parameter sweeps, and iterative data analysis. The research associate will work closely with collaborators to support materials investigations on NbN and the identification of lossy defects.

The work location for this position is at the NIST campus in Boulder, Colorado and also at the Boulder Cryogenic Quantum Testbed on the campus of University of Colorado in Boulder, Colorado. The research associate will also be encouraged to travel to present results at scientific conferences and to off-site experiments where NIST-built instruments are employed.
