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.

As an international team of researchers under major cooperation of the Universitiy of Innsbruck reports, extreme weather events play an important part in the global carbon balance. Their They resume a self-reinforcing effect between extreme weather events and climate change.

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.

Greenhouse gases emitted today will cause sea level to rise for centuries to come. Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows. While thermal expansion of the ocean and melting mountain glaciers are the most important factors causing sea-level change today, the Greenland and Antarctic ice sheets will be the dominant contributors within the next two millennia, according to the findings.

A team of quantum physicists in Innsbruck led by Christian Roos and Cornelius Hempel have realised an extremely sensitive method for the spectroscopy of atomic and molecular atoms. This technique can be used to closely study a number of particles. The scientists have published their findings Photonics.

The quantum physicists in Innsbruck welcome an addition to their team: Gerhard Kirchmair - a young aspiring physicist who brings a new technology to the Tyrol. The young scientist will investigate quantum mechanical phenomena by using superconducting circuits to build hybrid architectures for quantum information processing.

Innsbruck physicists led by Rainer Blatt and Peter Zoller experimentally gained a deep insight into the nature of quantum mechanical phase transitions. They are the first scientists that simulated the competition between two rival dynamical processes at a novel type of transition between two quantum mechanical orders.

Signaling cascades communicate and integrate extracellular signaling cues spatially and temporally via formation of defined protein-protein interactions. Scientists from the Institute of Biochemistry in Innsbruck discovered a unique mechanism which is based on binary protein-protein interactions and which explains cross talk between critically regulated signaling cascades.

Ninety-nine percent of all of Earth's land ice is locked up in the massive Greenland and Antarctic ice sheets. However, over the period 2003 to 2009, the melting of the world's other land ice stored in glaciers contributed just as much to sea level rise as the two ice sheets combined. This is the result of a new study led by Alex Gardner from Clark University (USA), which has been published in the current issue of the journal Science.

Second sound is a quantum mechanical phenomenon, which has been observed only in superfluid helium. Physicists from the University of Innsbruck, Austria, in collaboration with colleagues from the University of Trento and the National Research Council of Italy, have now proven the propagation of such a temperature wave in a quantum gas.

A team of physicists at the University of Innsbruck, Austria, performed an experiment that seems to contradict the foundations of quantum theory - at first glance. The team led by Rainer Blatt reversed a quantum measurement in a prototype quantum information processor. The experiment is enabled by a technique that has been developed for quantum error correction in a future quantum computer.

Not only do optical fibers transmit information every day around the world at the speed of light, but they can also be harnessed for the transport of quantum information. In the current , a research team of Innsbruck physicists led by Rainer Blatt and Tracy Northup report how they have directly transferred the quantum information stored in an atom onto a particle of light.

In micro electronics heat often causes problems and engineers have to put a lot of technical effort into cooling, for example micro chips, to dissipate heat that is generated during operation. Innsbruck physicists have now suggested a concept for a laser that could be powered by heat. This idea may open a completely new way for cooling microchips.

First Bose-Einstein condensate of erbium produced in Innsbruck Francesca Ferlaino's research team at the University of Innsbruck is the first to successfully create a condensate of the exotic element erbium. The Innsbruck experimental physicists hold the world record in attaining the first Bose-Einstein condensates of different chemical elements.

Methanol, water and a copper-zinc catalyst may be used to produce carbon monoxide depleted hydrogen, a power source for PEM (polymer-electrolyte-membrane) fuel cells, with high efficiency. By identifying the copper-zinc phase, which generates particularly clean hydrogen, Innsbruck scientists have cleared a hurdle for cutting-edge energy use.

Embargoed until 20:00 CEST Thursday , The physicists of the University of Innsbruck and the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck have come considerably closer to their goal to investigate complex phenomena in a model system: They have realized a digital, and therefore, universal quantum simulator in their laboratory, which can, in principle, simulate any physical system efficiently.

Repetitive error correction in a quantum processor A team of physicists at the University of Innsbruck, led by Philipp Schindler and Rainer Blatt, has been the first to demonstrate a crucial element for a future functioning quantum computer: repetitive error correction. This allows scientists to correct errors occurring in a quantum computer efficiently.

Physicists go beyond the limits of what is currently possible in quantum computation Quantum physicists from the University of Innsbruck have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced.

Atomic antennae transmit quantum information across a microchip The Austrian research group led by physicist Rainer Blatt suggests a fundamentally novel architecture for quantum computation. They have experimentally demonstrated quantum antennae, which enable the exchange of quantum information between two separate memory cells located on a computer chip.

A team of chemists headed by Thomas Loerting from the University of Innsbruck and Hinrich Grothe from the Vienna University of Technology (TU Wien) have prepared and isolated gas-phase carbonic acid and have succeeded in characterizing the gas-phase molecules by using infrared spectroscopy.
