More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology. Higher and higher radio frequencies are applied to transmit more data within shorter periods of time. Some years ago, scientists found that light waves might also be used for radio transmission. So far, however, manufacture of the small antennas has required an enormous expenditure. KIT scientists have now succeeded for the first time in specifically and reproducibly manufacturing smallest optical nanoantennas from gold.

These gold antennas act physically like radio antennas. However, the latter are 10 million times as large, they have a length of about 1 m. Hence, the frequency received by nanoantennas is 1 million times higher than radio frequency, i.e. several 100,000 GHz rather than 100 MHz.

These nanoantennas shall transmit information at extremely high data rates, because the high frequency of the waves allows for an extremely rapid modulation of the signal.

The crew of the classic science-fiction show's Starship Enterprise wore small devices on their chests that they could tap to communicate instantly with their colleagues. Such communications technology is now closer to reality thanks to a Finnish company which this week demonstrated high-tech clothing that can send and receive messages via satellite.

The demonstrator antenna, built by the Patria Aviation Oy company, looks like a simple patch of cloth but is capable of operating in the Iridium and GPS frequency band as part of clothing. The Iridium satellites allow two-way voice and data communication, while GPS provides positional data to the user. Iridium could also relay the position of the user.

According to the firm, the project's main issue was selecting the fabric to use because the material's electrical characteristics had to be measured using a number of techniques. This is not a completely trivial task and different measurement techniques have to be used in order to evaluate the validity of the extracted parameters, such as the systems ability to store electric capacity, what researchers called its dielectric constant. The next goal was to determine the antenna's performance when the wearer was moving around or bending.

In recent years, the Austrian physicist Anton Zeilinger has bounced entangled photons off orbiting satellites and made 60-atom fullerene molecules exist in quantum superposition--essentially, as a smear of all their possible positions and energy states across local space-time. Now he hopes to try the same stunt with bacteria hundreds of times larger.

Meanwhile, Hans Mooij of the Delft University of Technology, with Seth Lloyd, who directs MIT's Center for Extreme Quantum Information Theory, has created quantum states (which occur when particles or systems of particles are superpositioned) on scales far above the quantum level by constructing a superconducting loop, visible to the human eye, that carries a supercurrent whose electrons run simultaneously clockwise and counterclockwise, thereby serving as a quantum computing circuit.

But before technologies like quantum communications, computing, and metrology can realize their potential--a quantum Internet and uncounterfeitable money are two interesting possibilities--quantum networks must be able to transmit and store data. The quantum optics group at the California Institute of Technology has been working toward this goal.

Canonical, the company behind the popular Ubuntu Linux distribution, is preparing to launch a new Web service called Ubuntu One, which will bring cloud synchronization and collaboration features to the Linux desktop. The service is under heavy development, but it is expected to be ready for widespread use when Ubuntu 9.10, codenamed Karmic Koala, is released in October.

Canonical began inviting Ubuntu community members to participate in a closed beta test on Monday. Ars took it for a spin to see how it performs, also speaking with Canonical engineer Elliot Murphy and product manager Matt Griffin, who described the technology behind Ubuntu One and provided some insight into Canonical's future plans for the service.
Ubuntu One will support tight desktop integration.

To achieve that goal, the developers are building client software that will make the service a seamless part of the desktop experience. The software is currently available to beta testers in an Ubuntu Personal Package Archive (PPA) hosted on Launchpad. The source code will be released soon under open licenses and is said to be usable on other Linux distributions.

Call it the "one number to rule them all" service. Google Voice, which goes live in a few weeks, is supposed to let friends, relatives, and business contacts find you whether you're at your desk, on a business trip, or vacationing in Peru. Tests carried out over the past few days suggest that, despite a few glitches, it could well live up to this promise.

Users will soon be able to register, sign up for a phone number in a local area code, and add multiple landline and cell-phone numbers to an account. When someone calls a Google Voice phone number, all the registered phones ring at the same time.

The service takes several telephony technologies--voice-over-Internet Protocol (VoIP), voice transcription, and call routing--and connects them to the Web. Other Internet phone services let you play voice-mail messages on a computer or record calls, but Google Voice is a step towards unified communication. It's the voice equivalent of an e-mail address. Once you register a number, the idea is that you never have to worry about which phone you are using, even if you switch offices, homes, or cell phones.
