Google demonstrates quantum computer image search
12 Dec | New ScientistFull Text External Link Indicator
Google's web services may be considered cutting edge, but they run in warehouses filled with conventional computers. Now the search giant has revealed it is investigating the use of quantum computers to run its next generation of faster applications.
The Nobel Prize in Physics 2009
07 Oct | Nobelprize.orgFull Text External Link Indicator
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2009 with one half to Charles K. Kao, Standard Telecommunication Laboratories, Harlow, UK, and Chinese University of Hong Kong "for groundbreaking achievements concerning the transmission of light in fibers for optical communication" and the other half jointly to Willard S. Boyle and George E. Smith Bell, Laboratories, Murray Hill, NJ, USA "for the invention of an imaging semiconductor circuit – the CCD sensor"
Quantum computer closer: Optical transistor made from single molecule
07 Jul | GizmagFull Text External Link Indicator
"Researchers from ETH Zurich have recently managed to create an optical transistor from a single molecule in what is yet another important achievement on the road to quantum computing.

Quantum photonics is a particularly attractive field to scientists and engineers alike in that it could, once some core issues have been resolved, allow for the production of integrated circuits that operate on the basis of photons instead of electrons, which would in turn enable considerably higher data transfer rates as well as dramatically reduced heat dissipation."
Invisibility cloak modified to make you see things that aren't there
07 Jul | New ScientistFull Text External Link Indicator
AN ILLUSION device that makes one object look like another could one day be used to camouflage military planes or create "holes" in solid walls.

The idea builds on the optical properties of so-called metamaterials, which can bend light in almost any direction. In 2006, researchers used this idea to create an "invisibility cloak" that bent microwaves around a central cavity, like water flowing around a stone. Any object in this cavity is effectively invisible.
Invisibility cloak could hide buildings from quakes
01 Jul | New ScientistFull Text External Link Indicator
"Stefan Enoch and his team at the Fresnel Institute in Marseilles, France have been studying other applications for the physics behind invisibility cloaks. The result of their research is an “earthquake cloak” that could render objects “invisible” to shocks, storm waves or tsunamis."
Scientists create first electronic quantum processor
29 Jun | Eurekalert.orgFull Text External Link Indicator
A team led by Yale University researchers has created the first rudimentary solid-state quantum processor, taking another step toward the ultimate dream of building a quantum computer. They also used the two-qubit superconducting chip to successfully run elementary algorithms demonstrating quantum information processing with a solid-state device
Physicists Demonstrate Quantum Entanglement In Mechanical System
05 Jun | Science DailyFull Text External Link Indicator
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated entanglement—a phenomenon peculiar to the atomic-scale quantum world—in a mechanical system similar to those in the macroscopic everyday world. The work extends the boundaries of the arena where quantum behavior can be observed and shows how laboratory technology might be scaled up to build a functional quantum computer.
Bigger, better invisibility cloak appears
22 May | Purdue UniversityFull Text External Link Indicator
Researchers have created a new type of invisibility cloak that is simpler than previous designs and works for all colors of the visible spectrum, making it possible to cloak larger objects than before and possibly leading to practical applications in "transformation optics."
Illusion Cloak Makes One Object Look like Another
14 May | Technology ReviewFull Text External Link Indicator
"Fiddle with an invisibility cloak, and it can make any object look like another, say researchers. Just when you thought invisibility cloaks couldn't get any weirder, researchers come up with this: a way to make one object look like any other."
World first for sending data using quantum cryptography
15 Apr | PhysOrg.comFull Text External Link Indicator
For the first time the transmission of data secured by quantum cryptography is demonstrated within a commercial telecommunications network. 41 partners from 12 European countries, including academics from the University of Bristol, have worked on realising this quantum cryptographic network since April 2004.
