Job description

Associate Quantum Physicist (Quantum Computing) at Infleqtion, Louisville, Colorado, United States. A mid-level full time position in the Quantum Computing team, listed under hardware engineering.

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.

WORKING CONDITIONS and PHYSICAL REQUIREMENTS

Work will normally be performed in an office and laboratory environment and around technical equipment including computers and lasers. We ask that candidates be able to efficiently use automated office equipment such as laptops, copiers, and printers; able to effectively engage in communications (via phone, computer, or in-person). Any required Personal Protective Equipment will be provided and must be properly used in accordance with company requirements.

Responsibilities

Assemble, align, calibrate, operate, and maintain neutral-atom quantum computing systems and subsystems.
Execute defined R&D tasks involving quantum processor hardware, quantum-gate protocols, laser and optical systems, calibration, control, or system integration.
Translate experimental objectives into test procedures, measurement sequences, and data-analysis workflows with guidance from senior team members.
Conduct experiments, analyze data, compare results with physics-based models, and communicate conclusions to the broader team.
Develop and maintain Python-based tools for experiment control, data analysis, calibration, automation, and hardware integration.
Test and troubleshoot assigned equipment and subsystems using established diagnostic methods.
Document experimental procedures, system configurations, analysis methods, and results.
Support the commissioning, routine operation, maintenance, and continuous improvement of experimental systems.
Collaborate with physics, software, electrical, mechanical, and systems-engineering teams.

Requirements

Master’s degree in atomic, optical, AMO, quantum physics, or a related field, or a bachelor’s degree plus at least two years of comparable research or professional experience.
Hands-on experience conducting experiments involving atomic, optical, quantum, or precision-measurement systems.
Research or professional experience applying quantitative atomic or optical physics to experimental design, data analysis, or interpretation.
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.
Experience conducting and analyzing physics experiments or developing and testing 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 assembling, aligning, or maintaining laser and optical systems.
Experience with high-power or short-wavelength lasers and optical power-delivery systems.
Experience measuring laser-frequency, phase, pointing, or intensity noise.
Experience with analog electronics, RF systems, feedback control, or laboratory instrumentation.
Experience with high-numerical-aperture imaging, beam shaping, or optical projection.
Experience with ultra-high-vacuum systems or integrating optical, electronic, vacuum, control, and software subsystems.
Experience developing automated calibration, data-analysis, or experimental test tools.
