#Key component for terahertz wireless networks Terahertz radiation could one day provide the backbone for wireless systems that can deliver data up to one hundred times faster than today's cellular or Wi-fi networks.
But there remain many technical challenges to be solved before terahertz wireless is ready for prime time.
It's the technology that makes it possible for a single cable to carry multiple TV channels
or for a fiber optic line to carry thousands of phone calls at the same time.""Any terahertz communications application is going to need some form of multiplexing
Today's cellular and Wi-fi networks rely on microwaves to carry voice conversations and data. But the increasing demands for data transfer are quickly becoming more than microwaves can handle.
"For example, if one user suddenly needs a ton of bandwidth, you can take it from others on the network who don't need as much just by changing the plate spacing at the right location,

The computational elements in Safepay consist of a mobile device and a server which distributes disposable credit card numbers.
The physical entity is the magnetic credit card chip controlled by a mobile application inside a customer's mobile device.
The paper outlines the overall architecture and server-side deployment model the design of Safepay, prototype implementation and security analysis. Here's how it works:
First, the user downloads and executes the mobile banking application which communicates with the bank server.
During transactions, the mobile application acquires disposable credit card numbers from the bank server, generates a wave file,
plays the file to generate electrical current, and then drives the magnetic card chip via an audio jack
or Bluetooth The critical elements that make Safepay unique are: Disposable credit card information that expires after a limited time or number of usages (i e.,

This is an important step on the way towards optical computers. Phase change materials that change their optical properties depending on the arrangement of the atoms allow for the storage of several bits in a single cell.
With optical elements, computers can work more rapidly and more efficiently. Optical fibers have long since been used for the transmission of data with light.
But on a computer, data are processed still and stored electronically. Electronic exchange of data between processors and the memory limits the speed of modern computers.
To overcome this so-called Von neumann bottleneck, it is not sufficient to optically connect memory and processor,
as the optical signals have to be converted into electric signals again. Scientists, hence, look for methods to carry out calculations and data storage in a purely optical manner.
"The memory is compatible not only with conventional optical fiber data transmission, but also with latest processors,"Professor Harish Bhaskaran of Oxford university adds.
The new memory can store data for decades even when the power is removed. Its capacity to store many bits in a single cell of a billionth of a meter in size (multilevel memory) also is highly attractive.
Permanent all-optical on-chip memories might considerably increase future performance of computers and reduce their energy consumption.
"or transferred quantum information carried in light particles over 100 kilometers (km) of optical fiber, four times farther than the previous record.
Arraythe lead author, Hiroki Takesue, was a NIST guest researcher from NTT Corp. in Japan.
The new NTT/NIST teleportation technique could be used to make devices called quantum repeaters that could resend data periodically
perhaps enough to eventually build a"quantum internet.""Previously, researchers thought quantum repeaters might need to rely on atoms or other matter, instead of light,
the NTT/NIST experiment used quantum states that indicate when in a sequence of time slots a single photon arrives.
The experiments were performed at wavelengths commonly used in telecommunications. Because the experiment filtered out and focused on a limited combination of quantum states
Against the backdrop of healthy mouse tissue, rogue metastatic cells from the human tumor stick out like flares.
The researchers developed a new method using flow cytometry that let them capture individual human metastatic cancer cells traveling through the mouse's blood

-and-answer experiment Researchers used a brain-to-brain interface they developed to allow pairs of participants to play a'20 question'style game by transmitting signals from one brain to another over the Internet.
The respondent is shown an object (for example, a dog) on a computer screen, and the second participant,
With the click of a mouse, the inquirer sends a question and the respondent answers"yes"or"no"by focusing on one of two flashing LED LIGHTS attached to the monitor,
which flash at different frequencies. A"no"or"yes"answer both send a signal to the inquirer via the Internet
and activate a magnetic coil positioned behind the inquirer's head. But only a"yes"answer generates a response intense enough to stimulate the visual cortex
and cause the inquirer to see a flash of light known as a"phosphene.""The phosphene--which might look like a blob,
or by the brain signal transmission being interrupted by hardware problems.""While the flashing lights are signals that we're putting into the brain,

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,
since it is based on the same manufacturing technology as today's computer industry, "he added. The advance represents the final physical component needed to realise the promise of super-powerful silicon quantum computers,
which harness the science of the very small--the strange behaviour of subatomic particles--to solve computing challenges that are beyond the reach of even today's fastest supercomputers.
In classical computers, data is rendered as binary bits, which are always in one of two states:
A qubit operation exploits this quantum weirdness by allowing many computations to be performed in parallel (a two-qubit system performs the operation on 4 values, a three-qubit system on 8, and so on."
