The Innsbruck site has six research teams led by Rainer Blatt, Francesca Ferlaino, Rudolf Grimm, Gerhard Kirchmair, Hannes Pichler and Peter Zoller.

The Vienna site has seven teams, led by Markus Aspelmeyer, Časlav Brukner, Marcus Huber, Markus Müller, Miguel Navascues, Rupert Ursin, and Anton Zeilinger, as well as the recently established YIRGs (Young Independent Researcher Groups), led by Ämin Baumeler, Costantino Budroni, and Yelena Guryanova.

Thereby a close exchange of students and postdocs is established, and the members of the institute can be integrated into teaching at the universities.

The main research achievements of IQOQI-Vienna include the up-to-now longest quantum teleportation (over 144 km),[2] the highest photon angular momentum states that are entangled,[3] the coldest temperature of a nano-mechanical resonator[4] and the first proposal for testing general relativistic time dilation in a quantum experiment.

The building was previously the location of the Institute for Radium Research, now Stefan-Meyer-Institute for Subatomic Physics, initiated by Karl Kupelwieser and opened by Archduke Rainer of Austria.
