Senior Research Scientist, Silicon Spin Qubits

Q-CTRL • Los Angeles, CA

3d • $150,000 - $225,000

About The Position

The Quantum Computing Research team develops methods to improve the performance of contemporary and next-generation quantum computers. Its work includes quantum-computing applications, AI, control theory and physics-based optimization and automation, as well as research into quantum error correction and integration with high-performance computing and data centers.

The Senior Research Scientist will work with quantum scientists to develop software for calibration and optimization of quantum dot devices. The role focuses on robust routines for coarse tuning, calibration of high-fidelity single- and two-qubit gates, processor-scale optimization, and maintaining peak performance in real time. The scientist will collaborate with research, product, engineering, and other cross-functional teams to turn research insights into usable, production-level software tools and solutions.

The position includes cryogenic measurement and characterization of quantum dot-based qubits; developing and testing control protocols across device bring-up and gate optimization; creating scalable approaches to processor-wide optimization and real-time retuning; communicating research to colleagues and external partners; and contributing to product development and delivery.

Requirements

• Advanced degree in Physics, Engineering, or a closely related discipline; exceptional candidates with previous industry experience may also be considered.
• At least 3 years of research experience in a relevant field.
• Previous experience with tune-up and characterization of quantum dots.
• Expertise in numerical techniques, statistical learning, and optimization algorithms.
• Good grasp of software development best practices.
• Experience developing software modules for qubit measurement and control using Python, C++, or Rust.

Nice To Haves

• PhD in Physics, Engineering, or a closely related discipline.
• Familiarity with modern AI tools for software development.

Responsibilities

• Perform cryogenic measurements and characterization of quantum dot-based qubits.
• Invent, implement, and test control protocols for device bring-up, from coarse tuning through two-qubit gate optimization.
• Develop scalable protocols for processor-wide optimization, including cross-talk mitigation, leakage reduction, defect mitigation, and real-time retuning.
• Collaborate with engineering and product teams to translate ideas and research outcomes into production-level software.
• Explain, document, and present research solutions in accessible language.
• Engage with researchers at partnering companies and organizations to discuss current and future Q-CTRL calibration routines.
• Drive product development and delivery by translating research innovations into practical solutions.
