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.

Quality assurance for autonomous systems: TU Graz opens Christian Doppler lab
Quality assurance for autonomous systems: TU Graz opens Christian Doppler lab
In the new Christian Doppler Lab TU Graz develops methodologies for the quality assurance of cyber-physical systems. Together with corporate partner AVL List, this will be illustrated using autonomous vehicles as examples. From Smart Production and the Internet of Things to Robotics, cyber-physical systems combine electronics, software and mechanics and are linked together.

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.

Serious security vulnerabilities
Serious security vulnerabilities
An 10-strong international team of researchers - including researcher from TU Graz - has revealed two new vulnerabilities in computer processors: Meltdown and Spectre. PCs, server and cloud services are affected. A patch could help. Around the turn of the year speculation was rife about new, serious vulnerabilities that could affect all modern microprocessors.

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 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.

Upgrading the quantum computer 25.09.2015 Simulation of Chiral Edge States in a Quantum System
Theoretical physicists in Innsbruck have proposed a scalable quantum computer architecture. The new model, developed by Wolfgang Lechner, Philipp Hauke and Peter Zoller, overcomes fundamental limitations of programmability in current approaches that aim at solving real-world general optimization problems by exploiting quantum mechanics.

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.

Safe Cloud Computing is no Pie in the Sky
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.

Computer simulations visualize ion flux
Computer simulations visualize ion flux
Ion channels are involved in many physiological and pathophysiological processes throughout the human body. A young team of researchers led by pharmacologist Anna Stary-Weinzinger from the Department of Pharmacology and Toxicology, University of Vienna investigated how ion flux through a voltage gated sodium ion channel works in detail.

New Paths into the World of Quasiparticles
Quasiparticles can be used to explain physical phenomena in solid bodies even though they are not actual physical particles. Physicists in Innsbruck have now realized quasiparticles in a quantum system and observed quantum mechanical entanglement propagation in a many-body system.

This Sentence is Wrong
The great Viennese logician Kurt Gödel studied statements which refer to themselves - and his results shook the foundations of mathematics. "All Cretans are liars", said Epimenides, a Cretan. But this means that his statement must be a lie too. But then it is false that Cretans are liars and the statement must be true.

Your Computer is Stupid
The field of artificial intelligence is progressing. TU Vienna is a major center of this line of research. Several conferences on this topic will be held during the "Vienna Summer of Logic". The ball does not fit into the suitcase, because it is too small. What is too small? The ball or the suitcase? For humans the answer is evident, but computers still cannot handle such simple questions.
