Q-CTRL is looking to develop software solutions for calibration and optimization of quantum dot devices to improve the performance of quantum computers and accelerate pathways to useful quantum computers and other technologies.

Requirements

  • Previous experience in tune-up and characterization of quantum dots.
  • Expertise in numerical techniques, statistical learning, and optimization algorithms.
  • A good grasp of software development best practices, and experience in developing software modules for qubit measurement and control (Python, C++, Rust).

Responsibilities

  • Perform cryogenic measurements and characterization of quantum dot-based qubits.
  • Invent, implement and test novel control protocols for all the required bring-up steps starting from coarse tuning to optimizing two-qubit gates.
  • Develop scalable protocols for processor-wide optimization (e.g. cross-talk mitigation, leakage reduction, defects mitigation), and real-time retuning.
  • Collaborate with your colleagues in the engineering and product teams to translate ideas and research outcomes into production-level software.
  • Explain, document and present research solutions in accessible language.

Other

  • An advanced degree in Physics, Engineering, or a closely related discipline. A PhD is preferred, but we also consider exceptional candidates with previous industry experience.
  • 2 years of experience conducting research in a relevant field.
  • Flexibility: We embrace workplace flexibility so you worry more about your impact vs a rigid work schedule.
  • Make a dent: Last but not least you’ll have the unique opportunity to help set the direction for this revolutionary technology and truly make an impact that matters!
