Experimental AMO Physicist

Your mission

At planqc, we are building scalable quantum computers based on neutral atoms — one of the most promising platforms for achieving useful, fault-tolerant quantum computation.

This role is made for experimental AMO physicists who want to build state-of-the-art quantum computers.

You will bring your deep AMO expertise to the design, construction, characterization, and continuous improvement of our neutral-atom quantum processing unit. You will be part of a large, diverse team, working shoulder to shoulder with hardware engineers, software developers, electronics specialists, and quantum algorithm researchers.

Your responsibilities

• Design, build, characterize, and optimize state-of-the-art neutral-atom quantum computers

• Develop and execute measuring campaigns on the quantum processor, track system performance, and maintain stable operating conditions

• Investigate sources of noise, decoherence, and infidelity: systematically diagnose the limiting factors, propose and implement mitigation strategies

• Analyze experimental data rigorously to extract physical insight and guide system improvements

• Stay current with advances in AMO physics and quantum information science and bring relevant developments into the team's work

What you bring

• PhD or Postdoc in AMO physics

• Strong hands-on experience building or operating a neutral-atom platform or comparable hardware platforms

• Strong experimental instincts in systematic debugging and performance optimization

• Ability to take ownership of complex physical systems and drive them forward independently

• Excellent analytical skills and comfort working with experimental data

• Track record of peer-reviewed publications in AMO physics or quantum information

• Proficiency in experiment control, data acquisition, or data analysis (Python preferred)

• A research background in one or more of the following areas is a strong asset:

• Optical tweezer arrays / optical lattices

• Rydberg atoms

• Two-valence-electron atoms

• Atomic clocks or atomic interferometers

• Quantum gates and quantum computation with atoms

What characterizes you

• You are passionate about pushing the frontiers of experimental AMO physics

• You take ownership and drive complex physical systems forward independently

• You are rigorous and detail-oriented, and enjoy systematically diagnosing sources of noise and error

• You thrive in a collaborative, interdisciplinary team environment

• You are motivated by turning fundamental physics into real, working quantum hardware
