Wilhelm and Else Heraeus School

OQS 2023

4-9 June 2023
Hyytiälä, Finland

The exchange of energy and particles plays an important, sometimes even a decisive role in the physics of modern quantum devices. This is particularly true for mesoscopic solid state structures such as superconducting or semiconducting circuits. These are the systems that are also very attractive from the point of view of both theoretical analysis and experimental studies in modern laboratories.

The Summer School on Open Quantum Systems and Mesoscopic Physics is a carefully tailored intensive training, to provide participants with education in state-of-the-art experimental realizations and theoretical formulations of open quantum systems. Topics of the school include:

  • open quantum system theory of quantum integrated circuits
  • noise and thermodynamics in mesoscopic systems
  • many-body thermalization
  • quasiparticles in superconductors
  • quantum transport
  • quantum optics and electronics
  • topological semiconductors

The school is aimed at young scientists, graduate students, and postdoctoral researchers in the topics' disciplines. It provides an opportunity for immersive focusing on strengths and limitations of ‘deep’ quantum mechanical properties, observed and exploited in current and future experimental set-ups. The training consists of tutorials, collaborative seminar activities, poster sessions, flash talks, and contributed talks by local scientists.

Practical Info


The school takes place at the Hyytiälä Forestry Field Station of the University of Helsinki in Finland. The station is located approximately one hour north-east drive from the city of Tampere.

Hyytiälä has served as a university research station for over 100 years. Its historical buildings are an important part of Finnish cultural heritage, and have been conserved by the National Board of Antiquities and Historical Monuments. They are exceptional to serve still in their original purpose. New accommodation and dining buildings are opened for the field users during spring 2023.


Transportation between Helsinki and Hyytiälä will take place by a joint shuttle bus, organized for the school participants.

DEPARTURE: Sun 4 Jun at 6 PM, Mikonkatu Charter Bus Stop, Railway Square, Helsinki

International travel is to be organized by the participating students / sending host organizations.


Accommodation is provided in shared rooms for 2-4 persons.

Spare time activities

  • Nearby conservation areas and hiking tracks
  • Self-guided walk using a mobile device
  • Climate whirl - outdoor art
  • Lakeside saunas
  • Yard games
  • Fields suitable for football and beach volley
  • A scenic campfire place Makkarakallio about 500 m along a lakeshore track from the small sauna


Registration is open until March 31st 2023. All registered applicants will been informed on acceptance by a separate e-mail soon after the registration is closed.

Link to registration

The participation is free of charge. Accommodation, a daily warm lunch, coffee between sessions, as well as social program indicated in the program will be provided to the participants. Local transportation is provided by the organizers, while international travel must be arranged by the participants themselves.
