25 Years of Trapped Ions in Innsbruck Symposium in honour of Rainer Blatt’s 70th birthday

In celebration of the 70th birthday of Rainer Blatt, his 'cross of honour' from the state of Austria, 25 years of ion-trap based quantum optics and spectroscopy in Innsbruck (among other things to celebrate), the teams in Innsbruck are organising a symposium for Rainer.

We will have plenty of special guests such as the 'PhD-father' of Prof. Rainer Blatt: Guenter Werth, and friends attending such as Didi Leibfried, Piet Schmidt, Ferdi Schmidt-Kaler, Juergen Eschner, Christoph Becher, Rene Gerritsma, Lukas Slodicka, Markus Hennrich, Günter Werth, Jonathan Home, Klaus Boller, Cornelius Hempel, Uli Poschinger, Ekkehard Peik, Tommaso Calarco, ...



The guide to the venues of the symposium can be downloaded here: Link


These will take place at Karl-Rahner-Platz 3 (Jesuitenplatz), 6020 Innsbruck in the so-called ‘Leopoldssaal’.



Conference Dinner

We shall convene at the restaurant Bierstindl, Klostergasse 6, 6020 Innsbruck.
