Job Description


303 S Technology Ct, Broomfield, CO 80021

$106,000 – $134,000 a year

Join a team recognized for leadership, innovation and diversity

It is an incredibly exciting time to join the Quantinuum team, the world’s largest integrated quantum computing company!

Cambridge Quantum, the pioneer in quantum software, operating systems, and cybersecurity, and Honeywell Quantum Solutions, which has built the highest-performing quantum hardware, based on trapped-ion technologies, has combined and formed our company, Quantinuum.

We could be even better with you!

Career opportunities with Quantinuum abound: Scientists, engineers, marketing specialists, programmers, project coordinators and managers, business development specialists, business analysts… the list is long, and the room for growth is unlimited. Please browse the jobs below to see our US based positions.

At Quantinuum, we believe quantum information systems will revolutionize the way we work and live. We are leading the way by helping our customers develop quantum-enabled solutions that provide a competitive-edge in their markets.

We’re hiring the world’s best talent to make it happen. Join us!

We are seeking a Sr. Advanced Physicist in our newly created role for our Broomfield, CO location who will focus on research in quantum error correction in fully connected trapped-ion systems. A fully connected device is not beholden to the hardware geometry but can support error correction codes that are defined in arbitrary geometries, and we need your help in understanding how to best take advantage of this exotic system. A large-scale fault-tolerant quantum computer is still years away, but we are already laying the groundwork to integrate the technology into our systems. In this position, you will help define hardware and software requirements for both near-term and long-term goals. We seek to identify codes that can operate below the error pseudo-threshold in the trapped-ion architecture, demonstrate the ability in experiments, and understand how to integrate the codes into next generation machines. This position will involve working with other theorists and experimentalists to understand the noise environment, understand the impact of particular noise structures on different codes through analytic and numerical work, work with our software team to develop new programming tools for controlling logical qubits in the machines, designing and executing near-term experimental demonstrations, communicating results to the community through high-impact journal publications and conference presentations, investigating near-term uses quantum error correction techniques, and studying the full-integration of codes into large-scale machines. To apply directly, please follow the link below:


Key responsibilities:

  • Work with theory, software, and experimental teams to design and carry out quantum error correction technology demonstrations on existing quantum computers
  • Present findings to our larger team and outside community through technical presentations and journal publications
  • Work with AMO physics and architecture teams to find codes and hardware designs that work well together


  • PhD
  • Publication record in quantum error correction research
  • 1+ year of programming skills (Python preferred)
  • Applicants for employment for this position must have work authorization that does not now or in the future require sponsorship of a visa for employment authorization in the United States and with Quantinuum. (i.e., H1-B visa, F-1 visa (OPT), TN visa or any other non-immigrant status)


  • PhD in physics
  • Research experience in AMO physics, quantum verification and validation, quantum algorithms
  • High-performance computing experience
  • Experience in programming quantum computing hardware

Compensation & Benefits:

  • Not-Incentive Eligible
  • Salary Range: $106,000 to $134,000
  • Benefits: This role offers employment benefits, including health care*, 401k, vacation, and sick time.
