Postdoctoral Appointee-Magnon Dark-Matter quantum detection

Argonne National Laboratory · Lemont, IL · 3 wk ago
Analyst$73k–$121k/yrFull-time

Key Responsibilities

  • Develop superconducting hybrid circuits that couple to both macroscopic magnetic crystals as magnon target mass and solid-state single-electron qubit with magnetic field compatibility.
  • Develop superconducting hybrid circuits that couple to large single-crystal YIG spheres for optimizing magnon target mass and improving axion detector sensitivity.
  • Develop detector sensing demonstration experiments for measuring the quantum efficiency and dark count rates of magnon quantum detectors.
  • Develop novel quantum-limit devices based on high superconducting kinetic inductance with magnetic field tolerance, such as parametric amplifiers and qubits, for on-chip magnon quantum sensing.

Position Requirements

  • Superconducting resonator design, simulation and nanofabrication.
  • Microwave circuit design and characterization, including vector network analyzer, spectrum analyzer, or FPGA-based data acquisition.
  • Cryogenic measurements and equipment maintenance, preferably dilution refrigerator.
  • Knowledge about low-noise microwave characterization, including use of noise isolation components (circulator, isolator, attenuators, thermal anchoring, grounding).
  • Hand-in knowledge of designing and making sample holders and components for building new electronic experiments.

Experience

  • Ph.D degree in the field of Condensed Matter Physics, experimental High Energy Physics, Quantum Information Science, or a closely related discipline.
  • Demonstrated experience in quantum sensing, quantum information science, superconducting circuit, or magnonics.
  • Proficiency in scientific software development (e.g., Python, COMSOL, HFSS or similar languages).
  • Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork.
