The second law of thermodynamics states that entropy of the universe increases steadily over time. OeAW quantum physicists were able to show that timekeeping itself also contributes to it, as reported in the journal "Physical Review X".

We are pleased to announce the winner of the Paul Ehrenfest Best Paper Award for Quantum Foundations for the year 2016.

Mit einer Quantenverbindung quer über die Dächer von Wien konnten Forscher/innen der Österreichischen Akademie der Wissenschaften erstmals Quanteninformation mit mehreren Eigenschaften durch die Atmosphäre hindurch übertragen. Das berichten sie nun…

How can we certify the entanglement or nonlocality of a quantum system composed by infinitely many particles when we just have access to a finitely many? In a recent publication in Physical Review Letters, the IQOQI group led by M. Navascués answers…

Einsteins Äquivalenzprinzip ist für das Verständnis der Gravitation und der relativistischen Raumzeit von fundamentaler Bedeutung. Aus ihm folgt, dass unter dem Einfluss der Gravitation alle Körper in derselben Art und Weise fallen – sei es eine…

Einstein‘s „spooky action at a distance“ persists even at high accelerations, researchers of the Austrian Academy of Sciences were able to show in a new experiment. A source of entangled photon pairs was exposed to massive stress: The photons‘…

Our understanding of the world is mostly built on basic perceptions, such as that events follow each other in a well-defined order. Such definite orders are required in the macroscopic world, for which the laws of classical physics apply. However, in…

Clocks at the interplay of the two fundamental theories of modern physics

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…
