IQOQI Vienna

In the quantum laboratory...
...we ask Nature questions
We at the Institute for Quantum Optics and Quantum Information – Vienna (IQOQI-Vienna) of the Austrian Academy of Sciences are committed to advancing knowledge and enhancing human understanding of nature and its laws. We also actively pursue the vision of quantum information science and the wide range of new possibilities it would open up for humanity. To this end, we conduct theoretical and experimental research on the foundations of quantum physics and the physics of quantum information and develop new quantum technologies.

Researches experimentally demonstrated how an entanglement distillation scheme can be rethought to distribute quantum entanglement through noisy environments in a highly efficient manner.

A collaboration between Armin Tavakoli - postdoc at IQOQI Vienna - and researchers the University of Science and Technology of China, has shown that data collected in a single experiment can be used to robustly certify the entanglement of a quantum system under several different assumptions, all at…

Researchers from IQOQI-Vienna (Austrian Academy of Sciences) in the group of Rupert Ursin found a way to increase the secret key rate over long-distance links, distributed via wavelength-multiplexed entangled photons with unprecedented high rates. Their results are published in the journal IOP…

In den Gedankenexperimenten von Physiker/innen spielen hin und wieder allwissende und omnipotente Dämonen eine Rolle, wenn es darum geht, grundlegende Konzepte der Physik zu hinterfragen. Ein internationales Forschungsteam mit Beteiligung der ÖAW beweist in einer neuen Publikation im Journal…

The quantum movements of a small glass sphere could be controlled for the first time in Vienna by combining microscopy with control engineering, setting the course for future quantum technologies.

Seit kurzem ist es im Labor möglich, die Bewegung schwebender Nanoteilchen in den quantenmechanischen Grundzustand zu versetzen. Ein österreichisches Forschungsteam mit Beteiligung der ÖAW macht nun einen Vorschlag, wie die Quanteneigenschaften dieser Teilchen nutzbar gemacht werden können, bevor…
