Common goals, mutual interests – together with strong collaborators, we get closer our visions. We are proud to present our new Memorandum of Understanding

Scientists at the University of Vienna (Vienna Center for Quantum Science and Technology, VCQ) and the Austrian Academy of Science (IQOQI Vienna) have discovered a new method how to experimentally realize a manifold of different quantum states that…

Quantenphysiker der Österreichischen Akademie der Wissenschaften um Anton Zeilinger konnten mit Hilfe 600 Jahre alter kosmischer Lichtteilchen einen entscheidenden Beweis zur Quantenverschränkung erbringen. Im Fachjournal „Physical Review Letters“…

If a source emits photon pairs, their momenta can be correlated. For example, if one photon is always emitted in the exactly opposite direction of the other, the two photons show perfect correlation. On the other hand, the two photons could be…

The Paul Ehrenfest Best Paper Award for Quantum Foundations for the year 2015 was awarded jointly to three publications by groups at the TU Delft (The Netherlands), the Austrian Academy of Sciences (Austria) and the National Institute of Standards…

The research team around Anton Zeilinger has succeeded in breaking two novel records while experimenting with so-called twisted particles of light. In one experiment, the scientists could show that the twist of light itself, i.e. the screw-like…

Supraquantum theories - Is quantum mechanics a fundamental theory?

In 2015, three independent experiments, performed at TU Delft (the Netherlands), IQOQI Vienna (Austria), and NIST Boulder (USA), proved that nature is at variance with “local realism”. Albert Einstein called this phenomena “spooky action at a…

Researchers at the Institute of Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Universitat Autonoma de Barcelona have achieved a new milestone in quantum physics: they were able to entangle three particles of light…
