Institute for Quantum Optics and Quantum Information

The Institute for Quantum Optics and Quantum Information (IQOQI) (German: Institut für Quantenoptik und Quanteninformation) is a member institute of the Austrian Academy of Sciences and was founded in November 2003, to create an Austrian research center for the newly developing fields of theoretical and experimental quantum optics and quantum information. A branch in Vienna joined the Stefan-Meyer-Institute at Boltzmanngasse 3 under the direction of Anton Zeilinger.[1]

IQOQI Vienna

It has two independent sites in Innsbruck and Vienna with around 80 employees each. The institute is dedicated to fundamental research in quantum optics, quantum information, quantum foundations and quantum communication, both theoretical and experimental.

The site of Innsbruck has four research groups led by Rainer Blatt, Francesca Ferlaino, Rudolf Grimm and Peter Zoller and two junior groups led by Gerhard Kirchmair and Oriol Romero-Isart. The institute in Vienna (IQOQI-Vienna) has eight groups led by Markus Aspelmeyer (IQOQI-Vienna’s current director), Časlav Brukner, Marcus Huber, Markus Müller, Miguel Navascues, Rupert Ursin and Anton Zeilinger, as well as the recently established YIRG (Young Independent Researcher Group), lead by Ämin Baumeler, Costantino Budroni and Yelena Guryanova.[2]

The two sites are independent research centers with strong links to the University of Innsbruck and the University of Vienna. Thereby a close exchange of students and postdocs is established and the members of the institute can be integrated in teaching at the universities.

IQOQI-Vienna

The main research achievements of IQOQI-Vienna include the up-to-now longest quantum teleportation (over 144 km),[3] the highest photon angular momentum states that are entangled,[4] the coldest temperature of a nano-mechanical resonator[5] and the first proposal for testing general relativistic time dilation in a quantum experiment.[6] IQOQI-Vienna is a member of the Vienna Center for Quantum Science and Technology (VCQ).[7]

IQOQI-Vienna is located in a historical building at Boltzmanngasse 3. In May 2015, the European Physical Society has designated the building as an EPS Historic Site,[8] among the sites that are significant to physics and its history. 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.[9]
