Entanglement sent over 50 km of optical fiber
Entanglement sent over 50 km of optical fiber
For the first time, a team led by Innsbruck physicist Ben Lanyon has sent a light particle entangled with matter over 50 km of optical fiber. This paves the way for the practical use of quantum networks and sets a milestone for a future quantum internet. The quantum internet promises absolutely tap-proof communication and powerful distributed sensor networks for new science and technology.

Puzzling on a quantum chessboard
Puzzling on a quantum chessboard
Physicists at the University of Innsbruck are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. In a recent paper, they demonstrate that just a few quantum particles would be sufficient to solve the mathematically difficult N-queens problem in chess even for large chess boards.

Quantum Cloud Computing with Self-Check
Quantum Cloud Computing with Self-Check
With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.

For the future of quantum technology
For the future of quantum technology
BeyondC research project with partners from Austria and Germany starts in March The recently granted collaboration project "Quantum Information Systems Beyond Classical Capabilities (BeyondC)" coordinated by the University of Vienna will exploit the unique features of quantum science to go beyond the capabilities of classical technology.

Faster than allowed by quantum computing?
Faster than allowed by quantum computing?
Researchers determine the performance of multi-dimensional bits Quantum computers are more powerful than classical computers since they work with coherent "quantum bits" instead of ordinary zeroes and ones. But what if the laws of nature were different from what we think today - could there be even more efficient "science fiction computers"- Researchers from the Austrian Academy of Sciences and the University of Vienna have now shown that this is not possible - as long as those machines satisfy the same construction principles as ordinary circuits and their quantum counterparts.
