Scientists from the Max Planck Institute of Quantum Optics, Harvard University, and Caltech have succeeded in increasing the lifetime of a quantum bit (qubit) in a diamond crystal to over a second at room temperature. In earlier attempts, the storage time of this kind of qubit was only a few thousandths of a second.
The Hall effect has been observed for the very first time in a gas of ultracold atoms by researchers from the National Institute of Standards and Technology (NIST). This discovery will enable scientists to enhance their knowledge about the physics of the quantum Hall effect and superfluidity.

Daniel Grumiller and Gabriela Mocanu, researchers at the Vienna University of Technology, have devised a new technique to demonstrate the existence of theoretical ‘axions,’ which may encircle a black hole and extort energy from it. This may result in the emission of gravity waves, which can then be calculated.

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...
