Modern computers use this principle in practically Every bit (unit of measurement for the digital information content) and the almost unbelievable increase in performance over the last decade was based on a very simple rule:
faster processors and more storage space. Standard memory devices are based on electrons which are displaced by applying voltage.
because there is not just one storage device in our computers, but several optimised ones, depending on the task."
Rapid pattern recognition and a low energy consumption in connection with enormous parallel data processing would enable revolutionary computer architectures."
For the last 20 years, scientists have been attempting to create quantum systems that will outperform traditional semiconductor-based computers, the development potential
The main problem preventing the development of these computers is the high sensitivity of the nanoworld to external influences that destroy quantum states.

which holds the promise of solving problems a lot more efficiently than a classical computer. Physicists are now able to realize the basic building blocks,
and use them for simple computations. For practical application, a particular class of quantum computers, the so-called adiabatic quantum computer, has generated recently a lot of interest among researchers and industry.
It is designed to solve real-world optimization problems conventional computers are not able to tackle. All current approaches for adiabatic quantum computation face the same challenge:
The problem is encoded in the interaction between qubits; to encode a generic problem, an all-to-all connectivity is necessary,
"The programming language of these systems is the individual interaction between each physical qubit. The possible input is determined by the hardware.
This means that all these approaches face a fundamental challenge when trying to build a fully programmable quantum computer,
not only avoiding the limitations posed by the hardware but we also make the technological implementation scalable."
"Integrated fault tolerance Because of the increased number of degrees of freedom, which could also lead to nonphysical solutions,
"With this redundancy our model has also a high fault tolerance, "says Lechner. The new architecture can be realized on various platforms ranging from superconducting circuits to ultracold gases in optical lattices."

#Nanotechnology may double radio frequency data capacity A team of Columbia Engineering researchers has invented a technology--full-duplex radio integrated circuits (ICS)--that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception
networks can effectively double the frequency spectrum resources available for devices like smartphones and tablets."
Today's standards, such as 4G LTE, already support 40 different frequency bands, and there is no space left at radio frequencies for future expansion.
At the same time, the grand challenge of the next-generation 5g network is to increase the data capacity by 1, 000 times.
So the ability to have a transmitter and receiver reuse the same frequency has the potential to immediately double the data capacity of today's networks.
and bring this functionality to handheld devices such as cellular handsets, mobile devices such as tablets for Wifi,
and in cellular and Wifi base stations to support full duplex communications.""The biggest challenge the team faced with full duplex was canceling the transmitter's echo.

#Silicon photonics takes the next step toward a high-bandwidth future The computing and telecommunications industries have ambitious plans for the future:
Systems that will store information in the cloud, analyze enormous amounts of data, and think more like a brain than a standard computer.
Such systems are already being developed, and scientists at IBM Research have demonstrated now what may be an important step toward commercializing this next generation of computing technology.
They established a method to integrate silicon photonic chips with the processor in the same package,
avoiding the need for transceiver assemblies. The new technique, which will be presented 25 march at this year's OFC Conference and Exposition in Los angeles, California,
USA, should lower the cost and increase the performance, energy efficiency and size of future data centers, supercomputers and cloud systems.
Photonic devices, which use photons instead of electrons to transport and manipulate information, offer many advantages compared to traditional electronic links found in today computers.
Optical links can transmit more information over larger distances and are more energy efficient than copper-based links.
"IBM has been a pioneer in the area of CMOS integrated silicon photonics for more than 12 years,
"said Bert Offrein, manager of the photonics group at IBM Research-Zurich.""In addition to the silicon technology advancements at the chip-level, novel system-level integration concepts are required also to fully profit from the new capabilities silicon photonics will bring,
resulting in a large distance between the processor chip and the optical components. Offrein and his IBM colleagues from Europe
the United states and Japan instead proposed an integration scheme in which the silicon photonic chips are treated similarly to ordinary silicon processor chips
and are attached directly to the processor package without preassembling them into standard transceiver housings. This improves the performance
and power efficiency of the optical interconnects while reducing the cost of assembly. Challenges arise because alignment tolerances in photonics are critical (sub-micron range)
"Such systems will be key for future applications in the field of cloud-computing, big data analytics and cognitive computing.

Medical Doctors and students all around the world will be enabled to travel inside 3d cells in full color by simply downloading STEVE on their laptop declares Dr. Yann Cotte, CEO and cofounder of Nanolive SA.
which is developing a revolutionary microscope (and a revolutionary software) able to image and digitally stain living cells in 3d without any sample preparation and in real-time.
the company has developed unique software called STEVE. To mark and label certain parts of the measured cells in 3d,
the software allows the user to virtual brush and digitally paint the part of a cell based on their physical properties (called refractive index).
Stains panels can be modified constantly by the user, saved and reused for other cells of the same line.
As a result, the user has the possibility to measure authentic cells physiological activity, and, with the help of STEVE, she/he can discover its interior components, such as nucleus and organelles, on any screen and in a limitless amount of colors.
It takes just seconds to get up and running with the 3d Cell Explorer: the user only needs to switch on the microscope,
position the sample and initiate the analysis. The microscope instantly self-adjusts and, instantly, a full 3d image of the cell is displayed on the computer screen.

what computers would require far more time and energy to perform. What are these functions? Well, youe performing some of them right now.
the resulting device would have to be loaded enormous with multitudes of transistors that would require far more energy. lassical computers will always find an ineluctable limit to efficient brain-like computation in their very architecture,
said lead researcher Prezioso. his memristor-based technology relies on a completely different way inspired by biological brain to carry on computation.
however, many more memristors would be required to build more complex neural networks to do the same kinds of things we can do with barely any effort and energy,
The energy-efficient compact circuitry the researchers are striving to create would also go a long way toward creating the kind of high-performance computers
and memory storage devices users will continue to seek long after the proliferation of digital transistors predicted by Moore Law becomes too unwieldy for conventional electronics. he exciting thing is that,
