IQOQI

One Year After The Nobel Prize
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.
