Quantum Physicist

Infleqtion • Boulder, CO

181d • $115,000 - $165,000

About The Position

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.

Requirements

• PhD in atomic physics, optical physics, or related field; or equivalent related professional experience (4+ years).
• Proficiency in using tools commonly found in an atomic physics lab, such as lasers, acousto-optic modules, RF signal generators and analyzers, and ultra-high-vacuum systems.
• Proficiency in writing Python code for running physics experiments.
• Proficiency in calculating atom-light interaction for input laser specifications.
• Excellent verbal and written communication skills, ability to effectively share information with technical and non-technical staff at all levels of company hierarchy.
• Excellent collaboration skills, ability to work in an agile efficient team environment where engagement, feedback, and participation are an expected part of successful job performance.
• Demonstrated problem solving skills and fast learning rate.
• Ability to work both autonomously—taking high-level goals as input to develop and execute an optimal plan while gathering necessary resources—and collaboratively, by soliciting and incorporating input from colleagues.

Nice To Haves

• Experience in operating high power CW laser (> 1 Watt) and/or short-wavelength visible laser (< 500 nm) and designing their laser power delivery systems.
• Experience with characterization and mitigation of laser frequency and intensity noise.
• Experience with analog electronics and use of servo loops for laser and subsystem stabilization.
• Experience with image projection through a high numerical aperture (NA) imaging system.
• Experience in integrating heterogeneous subsystems for a complex physics experiment.
• Familiarity with Git, Linux, and command line interface (CLI) tools.
• Enthusiasm for staying up-to-date with latest developments in AMO physics and reviewing relevant papers for the team.

Responsibilities

• Design, build, calibrate and maintain Quantum Computers based on neutral atoms.
• Participate and/or lead Research and Development projects for laser systems, Quantum Processing Units, quantum gate protocols, etc. for Quantum Computers.
• Create, test, and validate mathematical models of atomic physics behavior, and use the results to inform system design by translating high-level system requirements into specialized engineering subsystems.
• Self-start and successfully execute on a new R&D activity given a well-defined goal and constraints (e.g. resources, timeframe): gather requirements from stakeholders, drive definition of solution space, drive project execution.
• Develop, test, run, and debug software for conducting experiments and system tuning in production.
• Design, assemble, and test laser and optical systems.
• Ownership of subsystems to maintain high availability and high performance.
• Mentor and teach junior team members as indirect reports. Supervise interns.

Benefits

• 100% company paid Employee coverage for Medical, Dental, Vision, and Short/Long Term Disability insurance programs.
• Employer funded Health Savings Account.
• Unlimited Paid Time Off.
• 401(k) Matching Programs.
• Company paid Life and AD&D Insurance.
• Flexible Healthcare Savings Account.
• Paid FMLA Leave.
• Paid Maternity/Paternity Leave.
• Employer Assistance Program.
• Student Loan Repayment.
