Quantum Physicist (Quantum Computing)

Infleqtion is on a mission to commercialize atom-based quantum technologies that deliver orders-of-magnitude improvements in sensing and computing applications. As a deep-tech startup, we embrace a results-driven, fast-paced, and customer-focused approach to innovation. We are seeking self-motivated, energetic individuals with exceptional problem-solving and technical skills to help drive our Quantum Computing mission forward. We encourage applications from experimental physicists with expertise in Atomic, Molecular, and Optical (AMO) physics, particularly those with experience in the coherent control of quantum systems such as ultracold atoms, trapped ions, and diamond NV centers.

Role and Responsibilities

• Design, build, calibrate, operate, and improve neutral-atom quantum computing systems and subsystems.
• Execute R&D projects involving quantum processor hardware, quantum-gate protocols, laser and optical systems, calibration, control, or system integration.
• Translate defined technical goals into experimental plans, subsystem requirements, and measurable performance targets.
• Design and analyze experiments and physics-based models to understand system behavior and guide technical decisions.
• Independently execute well-defined technical work from planning through implementation and validation.
• Develop Python-based tools for experiment control, data analysis, calibration, automation, and hardware integration.
• Own assigned subsystems through testing, troubleshooting, maintenance, documentation, and routine operation.
• Collaborate with physics, software, electrical, mechanical, and systems-engineering teams.
• Provide technical guidance to junior team members and supervise interns as appropriate.
