About this opportunity
Infleqtion lists this Staff Quantum Physicist opportunity in madison, Wisconsin. Review the employer’s description below for duties, qualifications and application requirements.
Job description
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
Lead the design, integration, calibration, operation, and improvement of neutral-atom quantum computing systems and critical subsystems
Translate program goals into technical requirements, experimental plans, performance targets, and technical direction across quantum processor design, Rydberg excitation, gate protocols, laser systems, calibration, and system integration
Design and analyze experiments and physics-based models to improve gate fidelity, stability, availability, and processor performance; guide architecture and engineering tradeoffs
Own critical systems through validation, troubleshooting, performance tuning, reliability improvement, and documentation; translate complex R&D objectives into prioritized work and drive cross-functional delivery
Develop Python-based tools in Linux environments for experiment control, data analysis, calibration, automation, and operational support
Review technical work and uphold team standards and best practices
Manage up to six direct reports, including expectations, performance, coaching, and career development.
Contribute to hiring, proposals, intellectual property, technical roadmaps, and external technical discussions
Requirements
PhD in atomic, optical, AMO, quantum physics, or a related field, or equivalent professional experience; typically 5+ years of relevant post-PhD experience or comparable experience leading complex quantum, atomic, optical, or precision-measurement systems
Deep hands-on experience designing, operating, or improving complex AMO or coherent-control experiments, with strong knowledge of atom-light interactions and technologies such as lasers, optical systems, acousto-optic or electro-optic modulators, RF instrumentation, and ultra-high-vacuum systems
Proficiency with Python for experiment control, data analysis, automation, or hardware integration, plus working knowledge of Linux, command-line tools, and version control
Demonstrated ability to turn ambiguous technical goals into executable plans and validated outcomes, lead system-level work across disciplines, and communicate effectively with specialist and non-specialist audiences
It is a plus if you have:
Experience with neutral-atom quantum computing, Rydberg physics, optical-tweezer arrays, quantum-gate characterization and optimization, or related processor architectures; familiarity with physical error mechanisms and quantum-error-correction requirements
Experience with advanced laser and optical systems, including short-wavelength lasers, beam delivery and shaping, optical projection, high-NA imaging, noise mitigation, feedback control, and subsystem stabilization
Experience integrating optical, electronic, vacuum, control, and software subsystems into complex experimental platforms
Demonstrated technical leadership through mentoring, cross-team coordination, and delivery of complex technical programs; experience contributing to proposals, patents, roadmaps, customer discussions, or government-funded R&D
