However the current systems, such as WLAN or Bluetooth have their limits: They transmit the data with clock rates of some gigahertz, maximum (a billion vibrations per second).
If one wants to increase the transmitted data quantity, then the clock rates must become still faster. Thus the range of the terahertz waves (1000 billion vibrations per second) has moved into focus - at least for short ranges, as for example, within rooms. However, thus far it has been extremely difficult here to produce and transmit enough transmitting power. That could change now.
Engineers and physicists of the Terahertz Communications Lab in Braunschweig, a cooperation of the Physikalisch-Technische Bundesanstalt (PTB) and the Technische Universität Braunschweig, have now - worldwide for the first time - successfully transmitted a video signal at a frequency of 300 GHz, over a distance of more than 22 meters, and have thus demonstrated that the transmission of user data is possible with terahertz waves.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
