Our In­sti­tute

Scientific excellence through structural networking

PhoQS serves as a central point for highly innovative interdisciplinary research. In addition to the strategic coordination of research activities, PhoQS provides the necessary infrastructure for interdisciplinary and forward-looking quantum research.

Ex­ec­ut­ive Board

The PhoQS Executive Board bundles central research management, joint strategic planning and the conception of teaching and transfer.

Learn more

Co­ordin­a­tion

In close consultation with the Executive Board, the Managing Director and Infrastructure Manager coordinate the activities of PhoQS. The PhoQS SupportCenter supports the members in the implementation and external presentation of research activities as well as in the promotion of interdisciplinarity and young researchers.

Learn more

In­fra­struc­ture

Fundamental to the interdisciplinary research work at PhoQS is a cross-institutional infrastructure. This is maintained by dedicated infrastructure teams.

Learn more

Young Tal­ents & Trans­fer

Through target group-oriented programmes, PhoQS not only promotes young scientists, but also creates a dialogue between society and science at an early stage.
