Recipe for a Universe
When soup is heated, it starts to boil. When time and space are heated, an expanding universe can emerge, without requiring anything like a "Big Bang". This phase transition between a boring empty space and an expanding universe containing mass has now been mathematically described by a research team at the Vienna University of Technology, together with colleagues from Harvard, the MIT and Edinburgh.

On the Horizon: A Quantum Internet
On the Horizon: A Quantum Internet
A team of scientists in Innsbruck, Austria, made an important step toward distributed quantum computing with cavities linking remote atom-based registers. They demonstrated precise control of the coupling of each of two trapped ions to the mode of an optical resonator. A key goal in quantum computing is the demonstration of a quantum network, that is, a framework for distribution and remote processing of quantum information.

Quantum computers: Trust is good, proof is better
A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology.

Creating Electricity with Caged Atoms
At the Vienna University of Technology, a new class of thermoelectric materials has been discovered. Due to a surprising physical effect they can be used to create electricity more efficiently. A lot of energy is wasted when machines turn hot, unnecessarily heating up their environment. Some of this thermal energy could be harvested using thermoelectric materials; they create electric current when they are used to bridge hot and cold objects.

Capturing brain activity with sculpted light
Researchers in Vienna develop new imaging technique to study the function of entire nervous systems Scientists at the Campus Vienna Biocenter (Austria) have found a way to overcome some of the limitations of light microscopy. Applying the new technique, they can record the activity of a worm's brain with high temporal and spatial resolution, ultimately linking brain anatomy to brain function.

An infallible quantum measurement
An infallible quantum measurement
For quantum physicists, entangling quantum systems is one of their every day tools. Entanglement is a key resource for upcoming quantum computers and simulators. Now, physicists in Innsbruck/Austria and Geneva/Switzerland realized a new, reliable method to verify entanglement in the laboratory using a minimal number of assumptions about the system and measuring devices.

Mirror, mirror on the wall, who has the lowest noise of them all
An international collaboration of scientists in Austria and the US demonstrate a novel "crystalline coating" technique for producing low-loss mirrors. This technology will further accelerate progress in the development of narrow-linewidth lasers. The work appears this week in an advanced online publication of Nature Photonics.

Taking the "Random" out of a Random Laser
Random Lasers are tiny structures emitting light irregularly into different directions. Scientists at the Vienna University of Technology have now shown that these exotic light sources can be accurately controlled. The light they emit is as unique as a fingerprint: random lasers are tiny devices with a light emission pattern governed by random scattering of light.

Heat Radiation of Small Objects: Beyond Planck’s Equations
Objects that are smaller than the wavelength of thermal radiation cannot radiate heat efficiently. A generalized theory of thermal radiation has now been experimentally confirmed at the level of a single object at the Vienna University of Technology. All the objects around us emit thermal radiation.

Improving Measurements by Reducing Quantum Noise
Researchers from Vienna University of Technology have built a new interferometer for trapped, ultracold atomic gases. By strongly suppressing the quantum noise, which ultimately limits the performance of interferometers, they were able to curb the effect of atomic interactions, and increase the interrogation time of their interferometer.

The Dance of the Atoms
Catalysts can stop working when atoms on the surface start moving. At the Vienna University of Technology, this dance of the atoms could now be observed and explained. Lone people standing in a ballroom don't tend to move a lot. It's only when they find a suitable dance partner that rapid motion sets in.

Helicopter-light-beams - a new tool for quantum optics
A light wave oscillates perpendicular to its propagation direction - that is what students learn in school. However, scientists of the Vienna University of Technology (TU Vienna) now perform atom-physics experiments with light oscillating in the longitudinal direction. Storing light in a bottle is easier than one might think: Laser light can be coupled into an optical glass fiber in such a way that it does not travel along the fiber but rather spirals around it in a bulged, bottle-like section.
