Why our body runs like clockwork
Why our body runs like clockwork
The friction in our joints is extremely low - how is that physically possible at all? Measurements at TU Wien provide explanations and ideas for new treatment methods . Friction and wear as an eternal nuisance - this is as familiar in technology as it is in medicine. Whether it's a manual transmission or a knee joint, you always want moving parts to slide over each other with as little friction as possible, so that energy expenditure and wear are kept to a minimum.

Engineering dual carriageways for signals
New possibilities for controlling signal routing in quantum information processing Routing signals and isolating them against noise and back-reflections are essential in many practical situations in classical communication as well as in quantum processing. In a theory-experimental collaboration, a team led by Andreas Nunnenkamp from the University of Vienna and Ewold Verhagen based at the research institute AMOLF in Amsterdam has achieved unidirectional transport of signals in pairs of "one-way streets".

World’s first chip with quantum architecture in use
Japanese IT company NEC has built the first quantum processor based on the ParityQC architecture. The Parity technology was invented at the University of Innsbruck and is being further developed and marketed by the spin-off ParityQC. NEC is now making the quantum computer, which specializes in optimization problems, available to the scientific community via the cloud.

Quantum physics secures digital payments
Quantum physics secures digital payments
Scientists from the University of Vienna have now designed an unconditionally secure system for shopping in digital settings Have you ever been compelled to enter sensitive payment data on the website of an unknown merchant? Would you be willing to consign your credit card data or passwords to untrustworthy hands? Scientists from the University of Vienna have now designed an unconditionally secure system for shopping in such settings, combining modern cryptographic techniques with the fundamental properties of quantum light.

Starting signal for the exploration of the invisible universe
Starting signal for the exploration of the invisible universe
Researchers at the University of Innsbruck are working intensively on preparations for the Euclid mission of the European Space Agency ESA. The space telescope will be launched on July 1 and is expected to produce the largest 3D map of the universe to date. Scientists hope to learn more about the hitherto unexplored dark matter and dark energy of the universe.

Shining potential of missing atoms
Shining potential of missing atoms
Single-atom vacancies in atomically thin insulators created in ultra-high vacuum Single photons have applications in quantum computation, information networks, and sensors, and these can be emitted by defects in the atomically thin insulator hexagonal boron nitride (hBN). Missing nitrogen atoms have been suggested to be the atomic structure responsible for this activity, but it is difficult to controllably remove them.

More complex than expected: Catalysis under the microscope
More complex than expected: Catalysis under the microscope
At TU Wien (Vienna, scientists use microscopy techniques to observe chemical reactions on catalysts more precisely than before yielding a wealth of detail. This made clear why some effects cannot be predicted. Catalysts composed from tiny metal particles play an important role in many areas of technology - from fuel cells to production of synthetic fuels for energy storage.

TU Graz researchers revolutionise production of biocompatible microfibres
By Falko Schoklitsch Using a newly developed method for the efficient and cost-effective production of biocompatible microfibres, the production of autologous skin and organs can be significantly accelerated. In biomedical technology, tissue engineering for the ex-vivo production of skin or organs is becoming increasingly important.

By adjusting knob to the quantum solid
Quantum physicists at the University of Innsbruck, together with colleagues at the ETH Lausanne, have found a new way to generate a crystalline structure that emerges as a "coherent matter density wave" in an atomic gas. The findings help to better understand the fascinating behavior of quantum matter near absolute zero.

Boost for the quan­tum inter­net
Boost for the quan­tum inter­net
A quarter of a century ago, theoretical physicists at the University of Innsbruck made the first proposal on how to transmit quantum information via quantum repeaters over long distances which would open the door to the construction of a worldwide quantum information network. Now, a new generation of Innsbruck researchers has built a quantum repeater node for the standard wavelength of telecommunication networks and transmitted quantum information over tens of kilometers.

Curved spacetime in a quantum simulator
Curved spacetime in a quantum simulator
New techniques can answer questions that were previously inaccessible experimentally - including questions about the relationship between quantum mechanics and relativity. The theory of relativity works well when you want to explain cosmic-scale phenomena - such as the gravitational waves created when black holes collide.

JUICE Magnetometer Successfully Commissioned in Space
JUICE Magnetometer Successfully Commissioned in Space
By ÖAW A sensor developed for JUICE in Graz delivers a first quantum interference signal about a month after the launch towards Jupiter, thus achieving an important mission milestone. The European Space Agency's JUpiter ICy moons Explorer (JUICE) spacecraft has achieved another milestone. It started its eight-year journey to the Jupiter system on 14 April 2023 to explore the largest planet in our solar system and its icy moons - Ganymede, Callisto and Europa - which may offer the essential requisites for life.

Artificial intelligence learns to control quantum particles
Artificial intelligence learns to control quantum particles
In quantum research, tailor-made electromagnetic fields are needed to precisely control particles. The TU Vienna has shown that machine learning is an excellent tool for this purpose . Tiny particles can be manipulated with electromagnetic fields: You can capture them, hold them, or move them to a specific location.

Scale separation: breaking down unsolvable problems into solvable ones
Scale separation: breaking down unsolvable problems into solvable ones
Exact solutions are often impossible in materials physics. In an international research cooperation involving TU Wien and Saitama University in Japan a technique has now been developed to make unsolvable quantum calculations solvable on certain scales. In physics, one often has to deal with different scales that can be described separately from one another: For the earth's orbit around the sun, it makes absolutely no difference whether an elephant in the zoo walks to the left or to the right.

Paradoxical quantum phenomenon measured for the first time
Paradoxical quantum phenomenon measured for the first time
How do quantum particles share information? A peculiar conjecture about quantum information has been experimentally confirmed at the TU Wien. Some things are related, others are not. Suppose you randomly select a person from a crowd who is significantly taller than the average. In that case, there is a good chance that they will also weigh more than the average.

Better superconductors with palladium
A Goldilocks material that might be just right: the precious metal palladium could be used to make superconductors that remain superconducting even at relatively high temperatures, show calculations by TU Wien. It is one of the most exciting races in modern physics: How can we produce the best superconductors that remain superconducting even at the highest possible temperatures and ambient pressure? In recent years, a new era of superconductivity has begun with the discovery of nickelates.

The quantum spin liquid that isn't one
The quantum spin liquid that isn’t one
The simplest explanation is often the best - this also applies to fundamental science. Researchers from TU Wien and Toho University recently showed that a supposed quantum spin liquid can be described by more conventional physics. For two decades, it was believed that a possible quantum spin liquid was discovered in a synthetically produced material.
