Description:
Xanadu is on a mission to build quantum computers that are useful and accessible to people everywhere. As part of the Hardware Team, you will work alongside a team of physicists and engineers to enhance the performance of photon number resolving (PNR) cryogenic detectors. Your expertise will contribute to optimizing transition edge sensors (TES) through clean room fabrication, cryogenic characterization, data analysis, and device simulations.
Key Responsibilities:
Research & Development:
- Optimize TES-based photon number resolving (PNR) cryogenic detectors.
- Conduct clean room fabrication and develop process recipes.
- Perform precision cryogenic measurements and data analysis.
- Develop and integrate large-scale TES PNR detector arrays into Xanadu’s hardware stack.
Fabrication & Testing:
- Utilize clean room tools such as photolithography, PVD, CVD, RIE, ICP, and wet etching.
- Characterize thin film devices using AFM, ellipsometry, and other metrology tools.
- Operate milli-Kelvin cryostats (dilution refrigerators) independently.
- Measure nanoamp/nanovolt level signals using analog testing equipment (VNA, spectrum analyzer, SMU).
Collaboration & Travel:
- Travel within Canada to partner facilities for clean room development.
- Work closely with internal stakeholders to align hardware development with critical system requirements.
- Contribute to team-based research and support large-scale device deployment.
Required Qualifications:
- PhD in Physics, Engineering, or Experimental Sciences with 2+ years of postdoctoral or industry experience.
- Expertise in clean room fabrication, photolithography, thin film deposition, and etching processes.
- Experience with precision measurements at nanoamp/nanovolt levels.
- Strong background in superconductivity physics and superconducting circuits.
- Independent operation of dilution refrigerators (milli-Kelvin cryostats).
- Proficiency in Python for data analysis and experiment automation.
- Ability to manage multiple projects in a fast-paced environment.
Preferred Knowledge & Experience:
- Knowledge of optical thin film stack metrology and optimization.
- Experience working with cryogenic detectors (e.g., CMB, TES, MKID, SNSPDs).
- Familiarity with guided wave optics and large data set analysis.
Why Join Xanadu?
- Be part of a team working on cutting-edge quantum computing technology.
- Hands-on research and development in a collaborative environment.
- Competitive compensation and benefits package.
- Inclusive, innovative, and growth-driven culture.
