#Quantum computers take a leap forward after scientists build qubit logic gate on silicon chip A major step towards building quantum computers capable of performing formidable calculations at a fraction of the speed of current machines has been achieved.
Computer scientists claim to have made a'game-changing leap'by building a logic gate a building block of a digital circuit using the strange properties of subatomic particles in silicon.
They say these could eventually lead to new types of quantum microchips that would revolutionise the digital world.
'We've demonstrated a two-qubit logic gate-the central building block of a quantum computer-and, significantly, done it in silicon.'
'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.''This makes the building of a quantum computer much more feasible,
Their work is the first time two qubits have been able to'talk'to each other in a logic gate.
On traditional microchips bits are stored typically on a pair of silicon transistors, one of which is switched on while the other is off.
In a quantum computer, data is encoded in the'spin, 'or magnetic orientation, of individual electrons. Not only can they be in one of two'up'or'down'spin states,
The key step taken by the Australian scientists was to reconfigure traditional transistors so that they can work with qubits instead of bits.
'The silicon chip in your smartphone or tablet already has around one billion transistors on it, with each transistor less than 100 billionths of a metre in size.'
'We've morphed those silicon transistors into quantum bits by ensuring that each has only one electron associated with it.'
A practical quantum chip could have a huge impact in areas where classical computers face an uphill struggle.

#ELECTRONIC SKIN can'feel'heat and pressure at the same time The unique way in which our fingertips can detect changes in both temperature
and pressure have been reproduced in an electronic'skin'.'In tests, the grooves in the e skin were able to respond to water droplets running across them
and could detect when a human hair was placed on their surface. The breakthrough could be used to make more lifelike prostheses
or improve the accuracy of wearable sensors and medical diagnostic devices. The electronic skin was developed by researchers at the Ulsan National Institute of Science
and Technology, led by Professor Jonghwa Park. Human skin contains unique epidermal and dermal microstructures and sensory receptors.
Existing electronic skin technology lets robots and robotic prostheses grasp and manipulate objects, discern the surface texture and hardness,
However, electronic skins that can simultaneously detect both heat and different types of pressure with a level of high sensitivity have been a difficult to develop, until now.
The authors tested the e skin's response to sensory changes created by water droplets and found that the skins can detect water falling at different pressures and temperatures.
Professor Park and colleagues said their e skin can be used to monitor pulse pressure by detecting the changes in skin temperature that occur

#Microfluidic cooling yields huge performance benefits in FPGA processors As microprocessors have grown in size and complexity,
One of the principle barriers to increasing CPU clocks is that it extremely difficult to move heat out of the chip.
Modern microprocessors generate tremendous amounts of heat, but they don generate it evenly across the entire die.
and CPUS aren very good at spreading that heat out across the entire surface area of the chip.

#MIT researchers announce new transistors for more power efficient electronics A material called gallium nitride (Gan) is poised to become the next semiconductor for power electronics,
Massachusetts institute of technology spin out Cambridge Electronics Inc (CEI) has announced a line of Gan transistors and power electronic circuits that promise to cut energy usage in data centres, electric cars,
Many of these power-electronics systems rely on silicon transistors that switch on and off to regulate voltage but, due to speed and resistance constraints,
CEI Gan transistors have at least one-tenth the resistance of such silicon-based transistors, which allows for much higher energy-efficiency.
While Gan transistors have several benefits over silicon, safety drawbacks and expensive manufacturing methods have kept largely them off the market.
Power transistors are designed to flow high currents when on, and to block high voltages when off.
But Gan transistors are typically ormally onmeaning, by default, theyl always allow a flow of current.
The researchers developed Gan transistors that were ormally offby modifying the structure of the material. e always talk about Gan as gallium and nitrogen
CEI is currently using its advanced transistors to develop laptop power adaptors that are approximately 1. 5 cubic inches in volume the smallest ever made.
Among the other feasible applications for the transistors is better power electronics for data centres run by Google
But Gan-based power electronics, Palacios said, could save a very significant fraction of that.
Another application will be replacing the silicon-based power electronics in electric car, Palacios said. These are in the battery chargers
and the inverters that convert the battery power to drive the electric motors. The silicon transistors used today have constrained a power capability that limits how much power the car can handle.
This is one of the main reasons why there are few large electric vehicles the researchers said. Gan-based power electronics, on the other hand, could boost power output for electric cars,
while making them more energy-efficient and lighter and, therefore, cheaper and capable of driving longer distances v
