Job Summary

The University of Colorado Department of Physics is encouraging applications for a Post-Doctoral Associate to perform experimental research aimed at understanding the effects of ionizing radiation on quantum circuits operated at millikelvin temperatures.
The University of Colorado Boulder is committed to building a culturally diverse community of faculty, staff, and students dedicated to contributing to an inclusive campus environment. We are an Equal Opportunity employer, including veterans and individuals with disabilities.

Who We Are

The Quantum Sensors Group, part of NIST’s Physical Measurement Laboratory, and the Quantum Electromagnetics Division, advances the detection of photons and particles in a variety of application areas using superconducting sensors and readout electronics. You will have access to cryogenic and fabrication facilities at NIST. Additional information about the QSG is available at the link below:

What Your Key Responsibilities Will Be

Develop a suite of specialized cryogenic detectors that are sensitive to individual radiation absorption events. These detectors will be able to:
  1. measure the energy deposited in superconducting circuits like qubits and their silicon substrates,
  2. count the number of quasiparticles created in superconducting films, and, possibly,
  3. measure the charge created in silicon substrates.

Measure the effects of both natural background radiation and man-made sources of photons and/or particles. Then use this data to assemble a definitive picture of how energy is deposited in millikelvin circuitry by background radiation.


The University of Colorado offers excellent benefits , including medical, dental, retirement, paid time off, tuition benefit and ECO Pass. The University of Colorado Boulder is one of the largest employers in Boulder County and offers an inspiring higher education environment. Learn more about the University of Colorado Boulder .

What We Require

  • A Ph.D. in physics, applied physics, or a similar field.
  • Experience operating multiplexed arrays of superconducting transition-edge sensors.
  • Experience with millikelvin cryogenics.
  • Experience in creating and performing radiation transport simulations.
  • Experience with a variety of scientific software, especially Python, C++, and Verilog.

Special Instructions

To apply, please submit the following materials:
  1. Resume/CV
  2. Cover Letter
  3. 1 Letter of Recommendation (Not Confidential)
  4. Proof of Degree/Transcripts

Review of applications will begin on Monday, October 5th.

Note: Application materials will not be accepted via email. For consideration, applications must be submitted through CU Boulder Jobs.
