Scientists have been working intensely on developing methods for quantum information transfer. This would enable tap-proof data transfer or, one day, even the linking of quantum computers. Quantum information transfer requires reliable information transfer from one quantum system to the other, which is extremely difficult to achieve. Independently, two research teams – one at the University of Innsbruck and the other at TU Wien - have ...

Scientists at Queen Mary University of London (QMUL) are bringing us closer to understanding the musical experience through a novel approach to analysing a common musical effect known as vibrato. Vibrato is the up-down oscillation in pitch introduced during instrumental or vocal performance, intended to add expressivity and to facilitate sound projection, and commonly used in opera.

IBM has announced its plans to begin offering the world's first commercial universal quantum-computing service—called IBM Q, the system will be made available to those who wish to use it for a fee sometime later this year. The system will build on IBM's Quantum Experience, a software development platform for programmers and developers interested in designing and building actual quantum-based applications.

A research group from Bar-Ilan University, in collaboration with French colleagues at CNRS Grenoble, has developed a unique experiment to detect quantum events in ultra-thin films. This novel research, to be published in the scientific journal Nature Communications, enhances the understanding of basic phenomena that occur in nano-sized systems close to absolute zero temperature.

A NASA technologist has teamed with the inventor of a nanotechnology that could transform the way space scientists build spectrometers, the all-important device used by virtually all scientific disciplines to measure the properties of light emanating from astronomical objects, including Earth itself.

Quantum replicants of responsive systems can be more efficient than classical models, say researchers from the Centre for Quantum Technologies in Singapore, because classical models have to store more past information than is necessary to simulate the future. They have published their findings in npj Quantum Information. The word 'replicant' evokes thoughts of a sci-fi world where society has replaced common creatures with artificial ma...

RJL Systems, a company based in Clinton Township, Michigan, launched last week the latest successor in their line of Bioelectrical Impedance Analysis (BIA) products, the Quantum V. The Michigan-based company, often considered the originators and chief innovators of BIA instrumentation for use in determining body composition, has regularly worked to advance their technology since the 1983 release of their initial FDA-cleared Class II medical devic...

Physicists at the National Institute of Standards and Technology (NIST) have cooled a mechanical object to a temperature lower than previously thought possible, below the so-called "quantum limit." The NIST theory and experiments, described in Nature, showed that a microscopic mechanical drum—a vibrating aluminum membrane—could be cooled to less than one-fifth of a single quantum, or packet of energy, lower than ordinarily p...

Researchers have developed a type of light-enhancing optical cavity that is only 200 nm tall and 100 nm across. Their new nanoscale system represents a step toward brighter single-photon sources, which could help propel quantum-based encryption and a truly secure and future-proofed network. Quantum encryption techniques, which are seen as likely to be central to future data encryption methods, use individual photons as an extremely secure wa...

For the first time, MIT physicists have observed a highly ordered crystal of electrons in a semiconducting material and documented its melting, much like ice thawing into water. The observations confirm a fundamental phase transition in quantum mechanics that was theoretically proposed more than 80 years ago but not experimentally documented until now.
