Senior Quantum Physicist - Quantum Sensing in Space

Infleqtion is a global quantum technology company solving the worlds most challenging problems. The company harnesses quantum mechanics to build and integrate quantum computers sensors and networks. From fundamental physics to leading edge commercial products Infleqtion enables quantum everywhere through our ecosystem of devices and platforms.

Location

Infleqtion has 6 office locations operating out of Boulder/Louisville CO; Madison WI; Chicago IL; Oxford UK; and Melbourne AU. This position is a full-time hybrid position which will be located in our Louisville CO office.

Position Summary

We are seeking a Senior Quantum Physicist to join our Emerging Technology team. This position will at least initially be in support of a technology demonstration mission in collaboration with NASA JPL/Goddard that will demonstrate a first-of-its-kind quantum gravity gradient (QGG) sensor on a dedicated satellite. Future opportunities and activities will include proposal writing acting as principal investigator for government or internal programs and contributing to the technical and product roadmaps associated with quantum inertial sensors based on atom interferometry.

The ideal candidate has experience modeling designing building and validating novel precision-measurement experiments or demonstrations of quantum sensing technologies. Specifically experience in atom interferometry and inertial/gravitational sensing would be ideal.

Key Responsibilities

• Participates in and/or leads research and development projects including but not limited to optical lattice vapor cells laser systems laser frequency stabilization and quantum sensing systems.

• Leverages physics expertise to inform technology and product roadmaps for inertial and gravitational sensing applications

• Proposal writing resource estimation and identification to determine program/project scope and execution

• Support business development customer conversations and negotiations

• Engage with the larger physics and engineering community at Infleqtion

• Coordinate across multi-disciplinary teams (physics engineering optical thermal systems manufacturing integration/test and company leadership).

• Help transition technologies based on ultracold atoms from R&D efforts to more robust engineered devices and ultimately deployed products

About the Team

Youll join a passionate and experienced team developing one of the worlds first space-deployable quantum gravity sensors. This effort is foundational to future navigation earth science and resource exploration missions.
