A team of researchers that include Silvano Garnerone, an IQC postdoctoral fellow, has shown a quantum speed-up to the PageRank algorithm, a key algorithm utilized by Google for ranking webpages based on their importance in the webgraph.

University of Bonn researchers have shown how one atom can be split into two halves, taken apart and then joined together again. The researchers strived to build quantum mechanics bridges by making the atom come into contact with adjacent atoms while it is being taken apart so that it functions like a bridge spanning between two pillars. The results are published in the "Proceedings of the National Academy of Sciences” journal.

Within the exotic world of macroscopic quantum effects, where fluids flow uphill, wires conduct without electrical resistance and magnets levitate, there is an even stranger family of "unconventional" phenomena...
In quantum physics physical processes in condensed matter and other many-body systems can often be described with quasiparticles. In Innsbruck, for the first time Rudolf Grimm’s team of physicists has succeeded in experimentally realizing a new quasiparticle - a repulsive polaron - in an ultracold quantum gas. The scientists have published their results in the online issue of the journal Nature.
Hundreds of string theorists meet each year to discuss their research at an international conference. STRINGS 2012 takes place in Munich, and is organized jointly by LMU Munich, the Max-Planck Institute for Physics, the ...
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.
The Volkswagen Foundation is financing a materials science project, being conducted under the aegis of Johannes Gutenberg University Mainz, to demonstrate the technical feasibility of a quantum computer on the basis of e...
Water is the most abundant and one of the most frequently studied substances on Earth, yet its geometry at the molecular level - the simple two hydrogen atoms and one oxygen atom, and how they interact with other molecules, including other water - has remained somewhat of a mystery to chemists.
Hector Bombin, Helmut Kraztgraber and Miguel Angel Martin-Delgado, researchers from the QUITEMAD Scientific Consortium (Technologies Program R & D, funded by the Community of Madrid) together with an international gr...
A study has turned upside down a typical way of looking at the connection between physics and information in quantum systems — with results that could lead to new insight into quantum computation.
Researchers at NIST have developed a novel way of producing light pulses that are "superluminal"—in some sense they travel faster than the speed of light. The new method could be used to improve the timing of communications signals and to investigate the propagation of quantum correlations.
Researchers have discovered that a process known as spontaneous emission that was previously seen as creating unhelpful noise in quantum data can be harnessed not only to protect the data, but even to compute.
In the age of high-speed computing, the photon is king. However, producing the finely tuned particles of light is a complex and time-consuming process, until now.
Thanks to the work by a team of engineers led by Profe...
