Quantum computing depends exquisitely on the parts of a quantum system remaining coherent long enough---even in the face of environmental noise---for the computation to be performed. A proposed scheme should be helpful in sustaining coherence by carefully making mid-calculation corrections.
In cooperation with his research group at the University of Kyoto and his partners in Freiburg, Prof. Dr. Osamu Tabata, microengineer and External Senior Fellow at the Freiburg Institute for Advanced Studies (FRIAS) is working on the development of a new generation of micromachines based on folded DNA molecules that is smaller, more intelligent and better than the previous generation.
Researchers have reported a new method for the lithography-free etching of complex surface motifs with the use of biodegradable polymers and enzymes. Starting with structured microchannels, they have built an assembly for the isolation and concentration of cells from whole blood.
As a laser material, Germanium together with Silicon could form the basis for innovative computer chips in which information would be transferred partially in the form of light. This technology would revolutionise data streaming within chips and give a boost to the performance of electronics.
Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires. Moreover, they combined these photonic switches into a logic gate, a fundamental component of computer chips that process information.
Scientists from the University of Aberdeen's Marine Biodiscovery Centre and the University of St Andrews presented their work on the components of a new type of computer chip created using molecules from a sea squirt sourced from the bottom of the Great Barrier Reef.
