About this role
Key Responsibilities:
- Develop and validate theoretical and numerical models of trapped-ion quantum operations, including laser–ion interactions, motional dynamics, and sources of error and decoherence.
- Analyze experimental data to identify performance limitations, test physical explanations, and recommend improvements to operating parameters, device control sequences, and calibration routines.
- Collaborate with system operators and engineers to design targeted experiments, interpret results, and implement and verify improvements on the hardware.
- Develop and maintain operation error models grounded in measured system behavior, identifying the dominant contributions and prioritizing opportunities for improvement.
- Perform analyses and design trade studies to inform hardware specifications, control approaches, and concepts of operation for future quantum computers.
- Build reusable modeling, analysis, and automation software, and communicate findings through actionable recommendations, technical documentation, presentations, and publications.
YOU MUST HAVE:
- PhD in physics or a closely related field, completed prior to the start date.
- Minimum of 8 years of experience, including PhD research, in atomic physics, quantum computing, quantum information, or closely related fields.
- Due to Contractual requirements, must be a U.S. Person defined as a U.S. citizen, permanent resident or green card holder, or worker granted asylum or refugee status.
- Due to national security requirements imposed by the U.S. Government, candidates for this position must not be a People's Republic of China national or Russian national unless the candidate is also a U.S. citizen.
WE VALUE:
- Strong foundation in the theory of atomic systems and coherent quantum control, with experience applying that knowledge to experimentally realized qubit systems.
- Deep understanding of trapped-ion quantum computing, particularly QCCD architectures and laser cooling.
- Strong scientific programming skills and experience developing software for modeling and data analysis.
- Experience collaborating closely with experimental scientists or engineers to translate theoretical analysis into practical changes in hardware operation.
- Experience modeling and mitigating experimental effects such as laser noise, drift, crosstalk, motional heating, and calibration errors.
- Experience benchmarking qubit operations and connecting measured performance to physical error mechanisms.
- Familiarity with experimental control systems, automated calibration, and the practical constraints of operating complex quantum hardware.
- Ability to work independently on open-ended problems and prioritize analysis based on its potential impact on system performance.
- Excellent communication skills, including the ability to explain physical mechanisms and recommendations to multidisciplinary teams, with published results in their field.
