A team at the University of Innsbruck, Austria has been successful in conducting electrons in metals along predetermined channels. This behaviour, observed for the first time in metals, provides important insights into the interactions of electrons - and on how the phenomenon of the current flow without any resistance loss, termed super-conductivity, can occur. Thereby this project aided by the Austrian Science Fund (FWF) combines fundamental research, at its best, with potential applications in the future.
High-temperature superconductors are ceramic materials that conduct electricity without resistance, and thus without loss, below a certain temperature. At higher temperatures, the behaviour rapidly changes and experiences resistance. Such discontinuous changes due to external influences are typical for the so-called "smart materials". Their discontinuous behaviour is closely linked with a mutual dependence of spatially confined electrons, giving rise to a commonly coordinated motion pattern. So far this dependence termed as correlation had been observed only in non-metals.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
