Bell’s theorem is a cornerstone of modern understanding of quantum theory. Over the last decade, the investigation of nonlocality has departed from the traditional scenario of the Einstein-Podolsky-Rosen paradox to focus on network scenarios, which…

The Paul Ehrenfest Best Paper Award for Quantum Foundations recognizes outstanding and influential research contributions to the foundations of quantum physics. We are proud to announce the paper winner of this year.

In quantum mechanics, not even time flows as you might expect it to A team of physicists at the Universities of Vienna, Bristol, the Balearic Islands and the Institute for Quantum Optics and Quantum Information (IQOQI-Vienna) has shown how quantum…

Some of the world’s most influential scientists conduct their research at IQOQI. According to the newest ranking by Clarivate Analytics, five out of 198 “Highly Cited Researchers” in physics are IQOQI members – an impressive number!

Im aktuellen GEO Magazin wird unter anderem Caslav Brukner vom IQOQI Wien zum Thema Quantenphysik und Realität interviewt

Researchers of the Navascués group at IQOQI Vienna have developed a mathematical framework to reason about adaptive protocols in quantum information theory. When they applied their theory to study entanglement detection, they found that the methods…

One of the most fundamental features of quantum physics is Bell nonlocality: the fact that the predictions of quantum mechanics cannot be explained by any local (classical) theory. This has remarkable conceptual consequences and far-reaching…

Quantum coherence only persists for isolated particles – but whether a particle is isolated depends on the way we look at it. This leads to an apparent “paradox of the third particle”: coherence seems to disappear simply by changing the description.…

“You run, we teleport”

Physicists at the Austrian Academy of Sciences and the University of Vienna have been successful in their experiments creating the world’s first photonic quantum teleportation into error corrected qubits useful for quantum computers.
