From years to days: Artificial Intelligence speeds up photodynamics simulations
Scientists use deep neural networks to achieve simulations on long time scales The prediction of molecular reactions triggered by light is to date extremely time-consuming and therefore costly. A team led by Philipp Marquetand from the Faculty of Chemistry at the University of Vienna has now presented a method using artificial neural networks that drastically accelerates the simulation of light-induced processes.

A new alphabet to write and read quantum messages with very fast particles
A new alphabet to write and read quantum messages with very fast particles
The interplay of quantum mechanics and special relativity requires a new alphabet to send reliable quantum messages Quantum information relies on the possibility of writing messages in a quantum particle and reading them out in a reliable way. If, however, the particle is relativistic, meaning that it moves with velocities close to the speed of light, it is impossible for standard techniques to unambiguously decode the message and the communication fails.

Quantum gravity's tangled time
Quantum gravity’s tangled time
The theories of quantum mechanics and gravity are notorious for being incompatible, despite the efforts of scores of physicists over the past fifty years. However, recently an international team of researchers led by physicists from the University of Vienna, the Austrian Academy of Sciences as well as the University of Queensland (AUS) and the Stevens Institute of Technology (USA) have combined the key elements of the two theories describing the flow of time and discovered that temporal order between events can exhibit genuine quantum features.

How to trick electrons to see the hidden face of crystals
How to trick electrons to see the hidden face of crystals
Researchers try a trick for complete 3D analysis of submicron crystals The 3D analysis of crystal structures requires a full 3D view of the crystals. Crystals as small as powder, with edges less than one micrometer, can only be analysed with electron radiation. With electron crystallography, a full 360-degree view of a single crystal is technically impossible.

When the pigeon and the letter do not travel together
When the pigeon and the letter do not travel together
In standard communication the pigeon always carries the message; the information is linked to a physical entity/particle. Counter to intuition, in a new counterfactual communication protocol published in NPJ Quantum Information, scientists from the University of Vienna, the University of Cambridge and the MIT have experimentally demonstrated that in quantum mechanics this is not always true, thereby contradicting a crucial premise of communication theory.

A connection between quantum correlations and spacetime geometry
A connection between quantum correlations and spacetime geometry
Researchers of the Academy explore the consequences of locality for measurements distributed in spacetime. Their article has now been published in the Nature journal "Quantum Information". Locality is a fundamental principle behind all physical interactions. It says that each physical system can only interact with other systems in its immediate vicinity, so that interactions between two distant objects must be mediated by an intermediary.

How to separate nanoparticles by
How to separate nanoparticles by "shape"
Physicists develop new strategy to separate molecules In our daily lives, the purpose and function of an item is defined by either its material, e.g. a rain jacket is fabricated of water-proof material, or its shape, e.g. a wheel is round to enable a rolling motion. What is the impact of the two factors on the nanoscale? The impact of material, i.e. the chemistry of the building block, has been excessively varied and the impact on polymer properties investigated leading to new functional materials, as for example slush powders.

Rapid destruction of Earth-like atmospheres by young stars
Rapid destruction of Earth-like atmospheres by young stars
Researchers show young stars rapidly destroy Earth-like Nitrogen dominated atmospheres The discoveries of thousands of planets orbiting stars outside our solar system has made questions about the potential for life to form on these planets fundamentally important in modern science. Fundamentally important for the habitability of a planet is whether or not it can hold onto an atmosphere, which requires that the atmosphere is not completely lost early in the lifetime of the planet.

Quantum Optical Cooling of Nanoparticles
Quantum Optical Cooling of Nanoparticles
When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, i.e. to cool it as close as possible to absolute zero temperature.

The Random Anti-Laser
The Random Anti-Laser
The concept of the laser can be reversed: the perfect light source then becomes the perfect light absorber. Scientists at TU Wien have found a way to build such an anti-laser, based on random scattering. The laser is the perfect light source: As long as it is provided with energy, it generates light of a specific, well-defined colour.

Superconduction: Why does it have to be so cold?
Superconduction: Why does it have to be so cold?
Currently, there is no precise computation method to describe superconducting materials. TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around -200°C Why does it always have to be so cold? We now know of a whole range of materials that ' under certain conditions ' conduct electrical current entirely without resistance.
