All prospective participants are kindly requested to register to the event by emailing one of the organisers. The event is in-person only (see Google map for location). No fees apply. We welcome submissions of poster abstracts.


The quantum-classical interface has always posed challenging problems in fundamental physics, with implications in a variety of different contexts, from thermodynamics to condensed matter systems, and the theory of gravity. Different manifestations of phenomena at this interface occur in both closed and open systems, which are studied by fully quantum and, in some cases, hybrid quantum-classical descriptions.

Within the project network Quantum Biology and the Arrow of Time, we are pleased to announce a one-day international meeting on the topic of “quantum-classical interface in closed and open systems”. This meeting is meant to bring together experts working on open quantum systems, hybrid quantum-classical systems, and related topics from different perspectives.

  • Ahsan Nazir (University of Manchester, UK)
  • Marcel Reginatto (National Metrology Institute, Braunschweig, DE).
