researchers have been trying to build a computer that harnesses the enormous potential of quantum mechanics. Now engineers from the University of New south wales (UNSW) in Australia have overcome the final hurdle,
by creating a quantum logic gate in silicon-the same material that today's computer chips are made from.
which means they now have the ability to build the world's first quantum processor chip and, eventually, the first silicon-based quantum computer.
Right now, regular computer chips store information as binary bits, which are either in a 0 or 1 state.
which isn't compatible with today's silicon-based computer infrastructure. A silicon quantum logic gate was the last physical building block remaining to be built
"Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs,
which rely on more exotic technologies, "project leader Andrew Dzurak said in a press release.""This makes the building of a quantum computer much more feasible,
since it is based on the same manufacturing technology as today computer industry.""The challenge in building quantum logic gates is the fact that,

A provisional patent has been secured on the technology, and a paper was published in the 17th ACM International Conference on Modeling, Analysis and Simulation of Wireless and Mobile Systems.
The capacity for printing silicon ink onto substrates has existed for some time, but necessitated a 350 C thermal annealing step--far too hot for many of the flexible surfaces that made production appealing in the first place.
Then we annealed the layer with an excimer laser a conventional tool used for manufacturing smartphone displays.
The most immediate application of this printing capacity is in wearable electronics as it allows for the production of fast, low-power and flexible transistors at a remarkably low cost.

"The experiments The experiments involved monkeys that were trained to reach for either of two targets on a computer screen.
while two jittering targets were positioned on either side of a computer screen. Colored barriers on the screen created a simple maze.
When the targets stopped jittering the monkeys were trained to move to one or the other target by sweeping his fingertip through the maze until he touched one of the targets.
During the experiments, 192 electrodes in each monkey's motor and premotor cortex began measuring brain activity the moment that the targets appeared on screen.

#Fiber-like light emitting diodes for wearable displays A research team at Korea Advanced Institute of Science
and Technology (KAIST) has developed fiber-like light emitting diodes, applicable to wearable displays. Professor Kyung-Cheol Choi and his research team from the School of Electrical engineering at KAIST have developed fiber-like light emitting diodes,
which can be applied in wearable displays. The research findings were published online in the July 14th issue of Advanced Electronic Materials.
Traditional wearable displays were manufactured on a hard substrate, which is attached later to the surface of clothes.
Such technique has posed limitations in applying it for wearable displays because inflexible displays were not adequate in practice,
and the characteristics of fabric were ignored. For a solution, the research team discarded the tradition of creating light emitting displays on a plane board.
Instead, they focused on fibers, a component of fabrics, and developed a fiber-like light emitting diode that has the characteristics of both fabrics and displays.
The essence of this technology, the dip coating process, is to immerse and extract a three dimensional (3-D) board that looks like a thread in a solution.
The researchers said that this technology would accelerate the commercialization of fiber based wearable displays

By modeling this process on a computer, the researchers found a good match with the experimental results.
