The Vienna research team led by Anton Zeilinger has achieved a new milestone in the history of quantum physics: The scientists were able to generate and measure the entanglement of the largest quantum numbers to date. To this end, the researchers…

One of the most deeply rooted concepts in science and in our everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. If an event A is a cause of an…

Physicists at the University of Vienna and the Austrian Academy of Sciences have achieved quantum teleportation over a record distance of 143 km. The experiment is a major step towards satellite-based quantum communication. The results have now been…

An international collaboration led by a team of Viennese researchers shines new light on the question of the resources required for achieving quantum information processing. The scientists demonstrate that less demanding resources, which are easier…

Carolyn Christov-Bakargiev, die Kuratorin der documenta (13), hat bewusst auch wissenschaftliche Präsentationen in ihre Kunstschau integriert. Vor allem der Wiener Quantenphysiker Anton Zeilinger sorgt beim Publikum und bei Journalisten für großes…

Wie verrückt – zumindest nach herkömmlichen Erfahrungshorizont – die Quantenphysik sein kann, haben nun Physiker um Anton Zeilinger in einem in "Nature Physics" veröffentlichten Experiment demonstriert. Demnach können in der Quantenwelt zukünftige…

The article "Probing Planck-scale physics with quantum optics" (Nature Physics, doi:10.1038/nphys2262) by I. Pikovski, M. R. Vanner, M. Aspelmeyer, M. S. Kim & C. Brukner was highlighted by Physics Today: "An optical probe of quantum gravity?"…

Einstein’s theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale is so remote from current…

Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. They have performed an…
