Zusammenfassung

Infleqtion, Inc. in Madison, WI, seeks a highly skilled experimental physicist to advance neutral-atom quantum computing systems and subsystems. You will lead design, build, and optimization efforts for quantum hardware and control systems, working across physics, software, electrical, mechanical, and systems teams.

The role requires a PhD in a relevant field and hands-on experience with AMO/quantum experiments, lasers, and data-driven optimization, plus mentoring responsibilities.

Qualifikationen

• PhD or equivalent professional experience in atomic/optical/AMO/quantum physics or related field.
• Hands-on experience designing, building, and operating complex AMO/quantum-control experiments.
• Experience applying quantitative models to experimental design or laser/control systems.
• Familiarity with Linux, Git, and lab software-tools.

Aufgaben

• Design, integrate, calibrate, operate, and improve neutral-atom quantum computing systems and subsystems.
• Lead R&D projects involving quantum processor hardware, quantum-gate protocols, laser and optical systems, calibration, control, or system integration.
• Translate program goals into technical requirements, experimental plans, and measurable performance targets.
• Design and analyze experiments and physics-based models to identify performance limitations and guide technical decisions.
• Mentor junior team members and contribute to technical reviews and best practices.
• Develop Python-based tools for experiment control, data analysis, calibration, automation, and hardware integration.

Jobbeschreibung

Role and Responsibilities

• Design, integrate, calibrate, operate, and improve neutral-atom quantum computing systems and critical subsystems.

• Lead R&D projects involving quantum processor hardware, quantum-gate protocols, laser and optical systems, calibration, control, or system integration.

• Translate program goals into technical requirements, experimental plans, and measurable performance targets.

• Design and analyze experiments and physics-based models to identify performance limitations and guide technical decisions.

• Independently own critical systems through development, validation, troubleshooting, reliability improvement, and routine operation.

• Develop Python-based tools for experiment control, data analysis, calibration, automation, and hardware integration.

• Collaborate across physics, software, electrical, mechanical, and systems-engineering teams.

• Mentor junior team members and interns and contribute to technical reviews and team best practices.

• PhD in atomic, optical, AMO, quantum physics, or a related field plus at least two years of relevant post-PhD experience, or comparable professional experience developing complex experimental systems.

• Hands-on experience designing, building, and operating complex AMO, quantum-control, or precision-measurement experiments.

• Experience applying quantitative atomic or optical physics models to experimental design or to the specification of laser, optical, RF, or control systems.

• Hands-on experience with lasers and optical systems, together with related technologies such as acousto-optic or electro-optic modulators, RF instrumentation, imaging systems, or ultra-high-vacuum equipment.

• Experience using Python for experiment control, data analysis, automation, or hardware integration.

• Evidence of independently leading a substantial experimental project or owning a critical technical subsystem.

It is a plus if you have:

• Experience with neutral-atom quantum computing, Rydberg physics, optical-tweezer arrays, or quantum-gate characterization.

• Experience with advanced laser systems, optical beam delivery, high-NA imaging, beam shaping, or optical projection.

• Experience characterizing and mitigating laser-frequency, phase, pointing, or intensity noise.

• Experience with analog electronics, RF systems, or feedback control.

• Experience integrating optical, electronic, vacuum, control, and software subsystems.

• Experience developing automated calibration, health-monitoring, or experimental test infrastructure.

• Familiarity with Linux, Git, command-line tools, and collaborative software-development practices.
