TL;DR · RF/Microwave Researcher

The RF/Microwave Researcher joins the IBM Quantum team to develop advanced high-performance circuits and subsystems for quantum computing systems. This role focuses on the design and system integration of microwave components, specifically quantum limited and low-noise amplifiers and isolators within superconducting qubit readout chains. The successful candidate will contribute to developing novel superconducting qubit measurement systems while collaborating with a multi-disciplinary team to communicate technical ideas. Required expertise includes RF/microwave filter design for notch filters, bandpass filters, and diplexers, alongside mastery of EM modeling and circuit design tools like Keysight ADS, EMPro, Ansys HFSS, Cadence/Clarity, or COMSOL. Candidates should be familiar with vector network analyzers and potentially possess experience with superconducting parametric amplifiers, trilayer Josephson junction devices, and large collaborations to solve complex problems in the quantum computing domain.

What you'll do

  • Design advanced high-performance circuits and subsystems for quantum computing systems.
  • Develop novel superconducting qubit measurement systems and microwave components.
  • Design and integrate quantum limited and low-noise amplifiers and isolators in readout chains.
  • Perform EM modeling, circuit design, and layout using tools like ADS, HFSS, or COMSOL.
  • Utilize vector network analyzers and other test equipment to evaluate component performance.
  • Create and communicate technical ideas through high-quality writing and presentations.

What we're looking for

  • Doctorate Degree (preferred).
  • Demonstrated knowledge of RF/microwave filter design, including notch filters, bandpass filters, and diplexers.
  • Mastery of EM modeling, circuit design, and layout tools such as Keysight ADS, EMPro, Ansys HFSS, Cadence/Clarity, or COMSOL.
  • Familiarity with various test equipment, such as vector network analyzers.
  • Familiarity with superconducting parametric amplifiers or related devices (preferred).
  • Familiarity with trilayer Josephson junction devices or similar complex device architectures (preferred).
  • Prior experience working across large collaborations (preferred).
