The newly founded Quantum Technology Lab at the Paul Scherrer Institute (PSI) seeks an optical engineer for the construction of a quantum computer based on trapped atomic ions. The candidate will be involved in the development of complex optical systems including imaging, light modulation, and beam-delivery to detect and control the quantum states of individual atomic ions, including testing of quantum algorithms.


The result will be a scalable control of ion-qubits via optical pulses enabling this area of quantum computing to access systems of hundreds of qubits.

The team at PSI will closely collaborate with the TIQI group at ETH Zurich, which conducts state of the art experimental research in quantum information science and has a successful track record in developing and operating quantum computing systems. The strong synergies between the experience and infrastructure at ETH and the novel approach at PSI will benefit both efforts.

Job description

  • Development and improvements of the imaging systems required for the detection of ion strings with cameras and/or photomultiplier tubes
  • Development and maintenance of fiber-based/free-space optical beam paths for the control of individual ions within a string stored in ultra-high vacuum chambers or cryostats
  • Design of planar-fabricated nanophotonic waveguides integrated with surface-electrode ion traps
  • Work closely with a team of researchers and other research groups at PSI to generate a collaborative environment and ensure project success

This position offers early-career candidates a path to embed themselves into the rapidly emerging field of quantum technology, synthesizing interesting engineering with the latest physics, and provides exposure to a wide range of challenges and learning opportunities in a fast-moving research setting. Collaboration with and mentoring by more senior team members will be part of the working environment.

Your profile

  • Experience with free-space and fiber-based optics including acousto-optic and electro-optic modulators
  • Experience with tolerancing, assigning technical requirements on optical parts and drawing preparation
  • Knowledge of simulation software such as ZEMAX or COMSOL 
  • Experience of integrated optics and packaging

Because the candidate will be working with students and researchers in a rapidly-growing field, initiative, creativity, and excellent problem-solving skills are highly desirable. The person must possess excellent English communication skills; German knowledge is favorable, but not required. Recent ETH/EPFL graduates are encouraged to apply.
