- PhD in atomic, optical, AMO, quantum physics, or a related field, or equivalent experience (at least four years of comparable research or professional experience).
About the job
Designs, builds, operates, and improves neutral-atom quantum computing systems through experimental research, subsystem development, and Python-based control and analysis.
What you'll do
- Design, calibrate, operate, and improve quantum computing systems and subsystems; execute R&D involving processor hardware, gate protocols, lasers, calibration, and integration.
- Plan and analyze experiments and physics-based models, translating technical goals into subsystem requirements and measurable targets.
- Develop Python tools and own assigned subsystems through integration, testing, troubleshooting, documentation, and operation.
What they ask for
- PhD in atomic, optical, AMO, quantum physics, or a related field, or at least four years of comparable research or professional experience.
- Hands-on experimental experience with atomic, optical, quantum, or precision-measurement systems.
- Experience applying quantitative atomic or optical physics models and hands-on experience with lasers and optical systems and related technologies.
- Experience using Python for experiment control, data analysis, automation, or hardware integration; evidence of designing and analyzing experiments or developing an experimental subsystem.
Nice to have
- Experience with neutral atoms, trapped ions, Rydberg physics, optical tweezers, quantum-gate protocols, or another coherent-control platform.
- Experience with high-power or short-wavelength lasers, laser-noise characterization or mitigation, RF systems, imaging, subsystem integration, or collaborative software development.
