For our group at the University of Siegen (Germany) we are looking for a motivated PhD student or postdoc in the field of quantum information theory, foundations of quantum theory, and quantum optics. The group is led by three PIs (Otfried Gühne, Stefan Nimmrichter, Chau Nguyen) and the research topics include:
- theory of multiparticle entanglement and quantum networks,
- foundations of quantum mechanics and Bell nonlocality,
- thermodynamics of open quantum systems and quantum thermal machines,
- quantum metrology and quantum learning,
- matter wave interferometry, decoherence theory, quantum-classical
transition.
Applicants for a PhD position are expected to have a MSc in physics, experience in theoretical physics and interest in foundational questions of quantum mechanics. Applicants for a postdoc position are expected to have a significant research record in a relevant field. The funding for the positions comes from a project aiming to improve the quantum education in schools. Consequently, candidates are expected to be interested in organizing events for pupils and working knowledge in the German language is considered to be a plus.
Applications (including CV and a list of publications) for a postdoc position shall be sent to Chau Nguyen (Chau.Nguyen@uni-siegen.de); applications for a PhD to Stefan Nimmrichter (Stefan.Nimmrichter@uni-
siegen.de). The deadline for applications is July 5th, 2026, but later applications may also be considered.
