<p>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. For this theory-focused role, we encourage applications from physicists with expertise in theoretical or experimental Atomic, Molecular, and Optical (AMO) physics, particularly those with experience in the coherent control of quantum systems and design and characterization of quantum gates.</p> <p>Role and responsibilities</p> <ul> <li>Develop theoretical models of neutral-atom quantum systems to inform system architecture, gate design, and hardware requirements. </li><li>Work closely with experimental physicists and hardware engineers to translate physical models and performance targets into actionable system and subsystem requirements. </li><li>Analyze and quantify error mechanisms in quantum gates (e.g., decoherence, control errors, crosstalk, laser and atomic noise). </li><li>Design, simulate, optimize, and contribute to validation of protocols for quantum gates, calibration, error-mitigation, and compilation to improve fidelity, robustness, and scalability. </li><li>Build and maintain simulation, analysis, and optimization software used to predict system behavior and guide experimental design. </li><li>Support experimental efforts by interpreting data, diagnosing unexpected behavior, and proposing theory-driven mitigation or design changes. </li><li>Self-start and execute new theoretical and modeling efforts given well-defined goals and constraints; scope problems, prioritize approaches, and deliver results on realistic timelines. </li><li>Mentor and teach junior team members as indirect reports. Supervise interns. </li></ul>
