QUANTUM ENTANGLEMENT CONFIRMED WITH LIGHT FROM DISTANT QUASARS

The group of Anton Zeilinger at the Austrian Academy of Sciences and the University of Vienna published a new test of quantum entanglement using photons from distant astronomical objects. An experiment placed on the Canary Island of La Palma used two…

How quantum particles see space-time?

Einstein’s theory of gravity famously describes space-time as an elastic object, which bends and stretches in the presence of masses or energy, much like a garden trampoline. Yet, we never observe space-time directly, but only through its effect on…

Warping time in quantum theory

A researcher at the Austrian Academy of Sciences devises a beam of particles with the property to make the quantum state of the systems it interacts with leap backwards in time. The result is published in the prestigious journal Physical Review X…

VIENNESE RESEARCHERS DEMONSTRATE NEW CONCEPT OF MEASURING QUANTUM STATES

Quantum physicists of the Austrian Academy of Sciences developed a new method for the certification of high-dimensionsally entangled quantum systems. This new method enables more efficient and reliable certification compared to previous methods and…

EINSTEIN DISPROVED BY 100,000 "BELLSTERS"

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.

Q³Sat: IQOQI scientists propose quantum links to mini-satellites

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…

QUANTUM PHYSICS FOR EVERYONE

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.
