With over 2,000 employees, the university is one of the largest employers in the region and offers a unique environment for teaching, study, research and knowledge transfer.

We seek:

At the Chair of Quantum Optics, we have developed groundbreaking methods to control trapped ions using high-frequency radiation and use them as an elementary switching unit (a qubit) in a quantum computer. We research and develop this system and thus prepare the basis for novel types of scalable quantum computers.

In the Faculty IV: School of Science and Technology, Experimental Quantum Optics, we are looking for a researcher  as soon as possible at the following conditions:

  • 100% = 39,83 hours  
  • Pay grade 13  TV-L
  • limited the duration of 2 years

Your tasks:

Your research activities will focus on novel approaches and methods for quantum computers with trapped ions. Your tasks include:

  • Responsible planning, simulation and construction of innovative experimental apparatuses

  • Preparing and carrying out experiments with trapped ions, data analysis, and publishing scientific results

  • Guidance of other scientists in the team
  • Cooperation with national and international research partners and third-party funding agencies

Your profile:

  • University degree in physics
  • Doctorate in physics
  • Sound knowledge of quantum mechanics
  • Essential for successful participation in the above-mentioned project are a high level of interest in the task at hand, exceptional commitment and initiative, and a strong ability to work in an interdisciplinary team.
  • International publications and participation in academic exchange (conferences, reviews, research reports, etc.)
  • Experience in one or more of the following areas is desired: experimental quantum optics with atoms, molecules or solid-state based systems, quantum information processing, laser spectroscopy and -cooling, microwave technology, laser technology, optics, vacuum technology, control electronics, and computer control of experiments.
  • Very good knowledge of English

Our range of services:

  • Promotion of own scientific or artistic qualification according to the Wissenschaftszeitvertragsgesetz [act on temporary employment in higher education] (e.g. habilitation)
  • Close cooperation with a technology-leading start-up and other partners from science and industry, as well as networking in an emerging industry.
  • Diverse opportunities to take on responsibility and make a visible contribution in the research and teaching environment
  • A modern understanding of leadership and collaboration
  • Good work-life balance, for example, through flexible working hours and work location, as well as support with child care
