Do you like teamworking on exciting novel applications in experimental quantum information science and quantum networks? Then the new Quantum Network Node Group led by Stephan Welte at the University of Stuttgart could be ideal for you.

My new group works on implementing versatile quantum network nodes for applications in quantum communication and computation. These nodes consist of an optical cavity that contains an array of individually addressed atoms. The atoms are arranged into regular arrays with optical tweezers and act as stationary qubits which interact via photons propagating in the cavity. The group will focus on photon-mediated quantum information processing between the intra-cavity atoms, the generation of optical cluster states, and the realization of optical Gottesman-Kitaev-Preskill states. In the long term, it is planned to realize a quantum network with several nodes connected via glass fibers. 

The group offers work on exciting and novel experiments at the intersection between quantum computation and quantum communication science in an international research environment. A high degree of motivation and dedication to research is required, along with the ability to work in a research team. A background in quantum optics is advantageous, but not required. The new laboratory is located at the 5th Institute of Physics in Stuttgart. 

In your project, you will have the possibility to

• contribute to state-of-the-art quantum information science experiments

• work in an international research group

• acquire technical skills in optics, mechanical engineering, vacuum technology, programming,…

• improve your communication skills by presenting scientific results at international conferences and collaborators around the world 

• write scientific publications 

We are looking for highly motivated PhD, Master, and Bachelor students. 

Applications should be sent by e-mail to Dr. Stephan Welte (stephan.welte@pi5.uni-stuttgart.de)
