Quantum Physicist

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.

• 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.

• PhD in atomic physics, optical physics, or related field; or equivalent related professional experience (4+ years);
  If you have substantially more experience than this and are excited to apply, please do! We will also consider hiring at the
  Senior Quantum Physicist
  level.
• 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.

It is a plus if you have:

• 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
