The global quantum hands-on physics experiment "Big Bell Test" conducted in 2016 disproved Albert Einstein's verdict on the phenomenon of entanglement. With success, as the experiment’s publication in the science magazine "Nature" now confirmed.

Quantum communication (QC) offers numerous advantages to classical communication, one of which is unbreakable security. To provide global access to QC in the near future, quantum-compliant satellites are essential, however extremely expensive until…

At the „Lange Nacht der Forschung 2018“, Austria’s biggest public science event, researchers of the IQOQI Vienna explained what we know about the nature of light.

Do we really understand our detectors?

The 2018 Entropy Young Investigator Award was granted to Dr. Nicolai Friis, senior postdoc at the Institute for Quantum Optics and Quantum Information, Austrian Academy of Sciences, Austria.

Entanglement is of central importance for the new quantum technologies of the 21st century. A German-Austrian research team is now presenting the largest entangled quantum register of individually controllable systems to date, consisting of a total…

Researchers at the University of Vienna and the Austrian Academy of Sciences develop a new theoretical framework to describe how causal structures in quantum mechanics transform. They analyse under which conditions quantum mechanics allows the causal…

Light can propagate with complex spatial structures, which allow for encoding information beyond one bit per photon. This could significantly increase data rates compared to today's communication technology. To exploit this, however, new methods must…
