Project description

The Trapped Ion Quantum Technology Group at Stockholm University invites applications for postdoc´s to join our experimental trapped ion research. The aim of the postdoctoral position is to investigate open spin-boson systems with trapped ions. This position is part of the QuantERA project " Collective quantum phenomena in dissipative systems – towards time-crystal applications in sensing and metrology (CoQuaDis)".

The CoQuaDis project aims to study many-body phases in open quantum systems and to demonstrate their use in sensing and timekeeping. At Stockholm University, we realize such systems using crystals of trapped ions, which provide long trapping times, controllable interactions mediated by collective vibrations, and in-situ cooling. This enables stable operation and continuous readout of dissipative many-body phases. This highly controllable platform allows us to address fundamental questions in open quantum many-body dynamics.

The position is experimental and will be carried out within the Trapped Ion Quantum Technology Group at Stockholm University. It will involve close collaboration with theoreticians at the University of Tübingen, Germany and the IFISC, Mallorca, Spain.

We are looking for a candidate with interest to work on trapped ion quantum experiments. For more information about our group and current projects, please visit https://qtech.fysik.su.se/.

Main responsibilities

The position involves

• Performing precision measurements and data analysis of open quantum system dynamics in a trapped-ion system.
• Investigating novel applications of trapped-ion-based open-system quantum simulations.
• Close collaboration with theoretical teams at University of Tübingen and IFISC, Mallorca.
• Assistance in the supervision of PhD and Master’s students in the lab.
• Contribution to grant reports and documentation related to the QuantERA project CoQuaDis.

Qualification requirements

In order to qualify for a Postdoctoral position, applicants are required to hold a Swedish doctoral degree or an equivalent relevant degree from another country. The degree must have been completed no later than when the employment decision is made.

Assessment criteria

It is considered an advantage if the doctoral degree or an equivalent degree was completed no more than three years prior to the application deadline. Under special circumstances, an older degree may also be an advantage. Special circumstances refer to sick leave, parental leave, elected positions in trade unions, service in the total defense, or other similar circumstances, as well as clinical attachment or service/assignments relevant to the subject area.

In the appointment process, special attention will be given to skills and experience in experimental research in quantum optics or quantum information, experience in trapped ions or atoms, quantum simulations or precision laser spectroscopy.

We welcome applications from candidates with:

• A PhD in experimental physics, quantum optics, atomic physics, trapped ions or a related field.
• Strong hands-on experimental skills, particularly in laser systems, optics, and/or quantum control techniques.
• A willingness to collaborate with both experimentalists and theorists.

About the employment

The position involves full-time employment for a minimum of two years and a maximum of three years, with the possibility of extension under special circumstances. Start date as soon as possible or as per agreement.
