#Novel Use of WI-FI Signals to Power Remote Devices, named Powi-Fi The scientists from the University of Washington have devised a method to utilize Wi-fi signals to power a battery-free camera,
demonstrating the possibility of using Wi-fi signals to broadcast power to remote devices. They have named the new approach as'Powi-Fi'signifying'power over Wi-fi'.
'In a report published in the MIT Technology Review, Vamsi Talla, an Indian origin scientist along with colleagues at the University of Washington in Seattle have asserted that Wi-fi radio broadcasts are a form of energy
and a simple antenna with the receivers can pick up this energy. Talla demonstrated his claim by connecting an antenna to a temperature sensor
and placing it close to a Wi-fi router. The resulting voltage in the device was measured then
and it was observed for how long the device can operate on the remote power source. When the team connected a camera to their antenna
Talla informed,"The battery-free camera can operate up to about five meters from the router,
Moreover, the researcher claimed that the router could even power the camera through a brick wall.
The team also used Wi-fi signals to charge a Jawbone fitness device from a no-charge state to 41%charged state in 2. 5 hours.
The MIT report stated that power-over-Wi-fi could be the enabling technology that finally brings the'Internet of things'to life e

The Utah engineers have developed an ultracompact beamsplitter the smallest on record for dividing light waves into two separate channels of information.
and shuttle data with light instead of electrons. Electrical and computer engineering associate professor Rajesh Menon and colleagues describe their invention today in the journal Nature Photonics.
Silicon photonics could significantly increase the power and speed of machines such as supercomputers data center servers and the specialized computers that direct autonomous cars and drones with collision detection.
Eventually, the technology could reach home computers and mobile devices and improve applications from gaming to video streaming. ight is the fastest thing you can use to transmit information,
says Menon. ut that information has to be converted to electrons when it comes into your laptop.
In that conversion, youe slowing things down. The vision is to do everything in light. hotons of light carry information over the Internet through fiber-optic networks.
But once a data stream reaches a home or office destination the photons of light must be converted to electrons before a router
or computer can handle the information. That bottleneck could be eliminated if the data stream remained as light within computer processors. ith all light,
computing can eventually be millions of times faster, says Menon. To help do that, the U engineers created a much smaller form of a polarization beamsplitter
(which looks somewhat like a barcode) on top of a silicon chip that can split guided incoming light into its two components.
Before, such a beamsplitter was over 100 by 100 microns. Thanks to a new algorithm for designing the splitter
Menon team has shrunk it to 2. 4 by 2. 4 microns, or one-fiftieth the width of a human hair and close to the limit of what is physically possible.
The beamsplitter would be just one of a multitude of passive devices placed on a silicon chip to direct light waves in different ways.
By shrinking them down in size, researchers will be able to cram millions of these devices on a single chip.
Potential advantages go beyond processing speed. The Utah team design would be cheap to produce
mobile devices such as smartphones or tablets built with this technology would consume less power, have longer battery life
and generate less heat than existing mobile devices. The first supercomputers using silicon photonics already under development at companies such as Intel
and IBM will use hybrid processors that remain partly electronic. Menon believes his beamsplitter could be used in those computers in about three years.
Data centers that require faster connections between computers also could implement the technology soon, he says.

or light-based wireless communication While lasers were invented in 1960 and are used commonly in many applications,

more energy efficient and can potentially provide more accurate and vivid colors for displays like computer screens and televisions.
Ning group has shown already that their structures could cover as much as 70 percent more colors than the current display industry standard.
The technology under development is called Li-Fi for light-based wireless communication, as opposed to the more prevailing Wi-fi,
using radio waves. Li-Fi could be more than 10 times faster than current Wi-fi and white laser Li-Fi could be 10 to 100 times faster than LED based Li-Fi currently still under development. he concept of white lasers first seems counterintuitive
because the light from a typical laser contains exactly one color, a specific wavelength of the electromagnetic spectrum, rather than a broad-range of different wavelengths.
White light is viewed typically as a complete mixture of all of the wavelengths of the visible spectrum, said Ning,
those independent lasers cannot be used for room lighting or in displays, Ning said. single tiny piece of semiconductor material emitting laser light in all colors

the world of computing will undergo a revolution of sophistication, speed and energy efficiency that will make even our beefiest conventional machines seem like Stone age clunkers by comparison.
But, before that happens, quantum physicists like the ones in UC Santa barbara's physics professor John Martinis'lab will have to create circuitry that takes advantage of the marvelous computing prowess promised by the quantum bit("qubit),
"Unlike classical computing, in which the computer bits exist on one of two binary("yes/no,
It uses parity information--the measurement of change from the original data (if any)--as opposed to the duplication of the original information that is part of the process of error detection in classical computing.
That way the actual original information that is being preserved in the qubits remains unobserved. Why? Because quantum physics."
Therefore, in something akin to a Sudoku puzzle, the parity values of data qubits in a qubit array are taken by adjacent measurement qubits,
which essentially assess the information in the data qubits by measuring around them.""So you pull out just enough information to detect errors,
This development represents a meeting of the best in the science behind the physical and the theoretical in quantum computing--the latest in qubit stabilization and advances in the algorithms behind the logic of quantum computing."
