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.

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.

Artificial intelligence for better computer graphics
Artificial intelligence for better computer graphics
[ Florian Aigner At the TU Wien (Vienna), neural networks have been developed which make it much easier to create photorealistic pictures of a wide variety of materials. If computer-generated images are to look realistic, different materials have to be presented differently: The metallic sheen of a coin looks quite different from the dull gloss of a wooden plate or the slightly transparent skin of a grape.

String Art - from the Hand of a Robot
String Art - from the Hand of a Robot
String art is a technique for the creation of visual artwork where images emerge from a set of strings that are spanned between pins. Now, at TU Wien (Vienna) this work can be delegated to a robot - an example of a complex task that digital fabrication can solve. The basic idea of string art is simple: hooks distributed on a frame are connected by strings back and forth until they fuse to a perceptible image.

Transferring quantum information using sound
Transferring quantum information using sound
How can quantum information be transferred from one atom to another? A team of researchers from TU Wien and Harvard University has proposed using phonons - the quanta of sound. Quantum physics is on the brink of a technological breakthrough: new types of sensors, secure data transmission methods and maybe even computers could be made possible thanks to quantum technologies.

Keeping GPUs young
Keeping GPUs young
Graphics processing units (GPUs) are used for many computationally intensive tasks. Their aging process can be slowed by clever management, as TU Wien (Vienna) and University of California (Irvine) have now shown. Graphics processing units are not only used for displaying graphics. Today, they are frequently used for particularly challenging calculations - for example in scientific research or even Bitcoin-mining.

Fingerprints of quantum entanglement
Fingerprints of quantum entanglement
Quantum entanglement is a key feature of a quantum computer. Yet, how can we verify that a quantum computer indeed incorporates a large-scale entanglement? Using conventional methods is hard since they require a large number of repeated measurements. Aleksandra Dimić from the University of Belgrade and Borivoje Dakić from the Austrian Academy of Sciences and the University of Vienna have developed a novel method where in many cases even a single experimental run suffices to prove the presence of entanglement.

Logic can make our Browsers Safe
Logic can make our Browsers Safe
The Computer Scientist Matteo Maffei (TU Wien) is awarded an ERC Consolidator Grant for the project "Browsec: Foundations and Tools for Client-Side Web Security" . He is working on a plugin that will make browsers safe - and is logically impossible to fool. We are hardly aware of the dangers we face when we are browsing the web.

New tool for characterizing quantum simulators
New tool for characterizing quantum simulators
Physicsts are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers. However, they first need new tools to ensure that the simulators work properly. Innsbruck researchers around Rainer Blatt and Christian Roos, together with researchers from the Universities of Ulm and Strathclyde, have now implemented a new technique in the laboratory that can be used to efficiently characterize the complex states of quantum simulators.

Nickel is Crucial for the Earth's Magnetic Field
Nickel is Crucial for the Earth’s Magnetic Field
Scientists at TU Wien and Würzburg University are changing our idea of the earth's magnetic field: iron alone cannot explain the concept of the geodynamo. The crucial ingredient is nickel. It only takes a simple compass to demonstrate that the earth has a magnetic field - but it is quite difficult to explain how exactly it is created.

A new tool to decipher evolutionary biology
A new bioinformatics tool to compare genome data has been developed by teams from the Max F. Perutz Laboratories, a joint venture of the University of Vienna and the Medical University of Vienna, together with researchers from Australia and Canada. The program called ‘ModelFinder' uses a fast algorithm and allows previously not attainable new insights into evolution.

Improved interface for a quantum internet
A quantum network requires efficient interfaces over which information can be transferred from matter to light and back. In the current issue of Physical Review Letters, Innsbruck physicists led by Rainer Blatt and Tracy Northup show how this information transfer can be optimized by taking advantage of a collective quantum phenomenon.

The integration of digital expert knowledge and automation of risk analyses can greatly improve software test procedures and make cloud computing more secure. This is shown by the latest results of a project of the University of Innsbruck, funded by the Austrian Science Fund FWF, on the quality assurance of security critical systems which have recently been published.
