Quantum Theorist, Atomic Physics Focus (Denmark)
Atom Computing
Copenhagen, Denmark
Posted on Oct 24, 2025
At Atom Computing, we build quantum computers using arrays of optically trapped neutral atoms that will empower customers to achieve unprecedented computational breakthroughs. Work alongside our Quantum Engineering, Control Systems, and Software teams to demonstrate the power of scalable, neutral-atom quantum computers.
We are seeking a Quantum Theorist to contribute to a variety of projects that help with the development of neutral atom quantum computing. As a Quantum Theorist at Atom Computing, you will join a team of talented scientists and engineers who are working to translate fundamental atomic physics to a scalable, fault-tolerant quantum computer.
Job Responsibilities:
- Conduct independent and collaborative theoretical and computational projects that drive the understanding and development of neutral atom quantum computers.
- Contribute to the development and operation of a variety of atomic physics simulations and translate them into high-quality, maintainable software solutions.
- Collaborate with Experimentalists, Quantum Engineers, Error Correction Theorists, and AMO Theorists to model experimental results, develop noise models for quantum hardware, and contribute to the design of neutral-atom quantum computers.
- Write clean, well-tested, and documented code in multiple languages (preferrably Python, Julia, or C++).
Experience & Education:
- PhD in Physics, Mathematics, Chemistry, Engineering, Computer Science or a related field.
- Experience with scientific, high-performance, or quantum computing.
Qualifications:
- Deep understanding of atomic, molecular and optical physics.
- Excellent written and oral communication skills, with published results within their field of research.
- Technical expertise spanning Atomic structure, quantum optics, and qubit control using e.g. QutiP, QuantumOptics.jl, Mathematica, or equivalent.
- Willingness to learn modern software development practices: version control (Git/GitHub), unit testing, continuous integration, and documentation.
- Temperamentally suited to work at a fast-growing, early stage startup: self-motivated, humble, driven, collaborative, and has a high tolerance for ambiguity and uncertainty.
