Origin Of Quantum Computing

simultaneously


As technology evolves, it increases the scale of integration and fit more transistors into the same space; and increasingly smaller microchips are made, and that is, the smaller, faster process reaches the chip. However, we can do infinitely small chips. There is a limit at which stop working correctly. When it comes to the scale of nanometers, the electrons escape of the channels through which must circulate. This is called tunneling.

A classical particle, if it encounters an obstacle, can not cross it and bounces. But with electrons, which are quantum particles and behave like waves, there is a possibility that a part of them can pass through the walls if they are too thin; so the signal can go through channels where it should not flow. Therefore, the chip stops working properly.

Consequently, the traditional digital computation would soon reach its limit, since it already has reached scales of only a few tens of nanometers. This raises the need for new technologies and that is where quantum computing comes in.

The idea of ??quantum computation arises in 1981 when Paul Benioff set out his theory to harness the laws of quantum computing environment. Instead of working at the level of electrical voltages, working-level terms. In the digital computing, a bit can take only two values: 0 or 1. However, in quantum computing, involving the laws of quantum mechanics, and the particle can be in coherent superposition: it can be 0, 1, and may be 0 and 1 at a time (two orthogonal states of a subatomic particle). This allows several operations can be performed simultaneously, depending on the number of qubits.

The number of qubits indicates the number of bits that can be superimposed. With conventional bits, if we had a record of three bits, there were eight possible values ??and the registry only could take one of those values. But if we have a vector three qubits, the particle can take eight different values ??at the same time thanks to the quantum superposition. Thus a three qubits vector allow a total of eight parallel operations. As expected, the number of operations is exponential with respect to the number of qubits.

To get an idea of ??breakthrough, a quantum computer of 30 qubits would amount to a conventional processor 10 teraflops (10 trillion floating point operations per second) when the computer is currently working on the order of gigaflops (billion operations).

Top 10: The Best Smartphones

smartphone

True, Apple and Samsung are still the favorite of many, however, there are options that can not pass unnoticed.

The main brands of smartphones in the world and have their strengths to continue the competition this year letters, some are old acquaintances of this list and its new versions are kept in the taste of users or even attract other gadget lovers.

So star review and we revise our list of the best smartphones that can be achieved during the first quarter of 2015, and here we show the features that shine from each of these devices.

Some are not available in Mexico until April -other could take a more-weeks, but their releases and placed in the center of the stage and will certainly be among the most sought by users.

Bluetooth

bluetooth


Bluetooth technology is an open specification for wireless communication (WIRELESS) data and voice. It is based on a radio link low-cost, short-range, implemented in an integrated circuit 9 x 9 mm, providing (ad hoc) connections for instant mobile communications environments both as static. In short, Bluetooth aims to be a global specification for wireless connectivity.

Within the field of technology and its application is immediate communication that allows: easy, instant, anywhere and its cost is low. Without forgetting its impact on the way of making processes by replacing conventional media and enable new businesses and applications.

Similarly, its application will be expanded and fruitful in the Industrial Sectors:

Automotive, Aeronautical, Naval, other transports.

Real mechanical / electrical / Appliances equipment.

Computers, office / home.

Telecommunications and electronic equipment.

Other industry segments

Finally, we can not forget the space begins to fill in Services Sectors:

Financial.

Contents / leisure.

Administration and public services.

Private business services.

Differences between 3G and 4G

3g 4g



4G is a technology with which the data download speed is increased substantially compared to 3G:

Between 5 and 10 times faster than 3G download speeds.
Up to 3 to 4 times faster response time (latency) and substantially improves the experience, for example, in online games.
These improvements in the connection speed will substantially improve the service experience video games and high-definition (HD).

Laptop

laptop



A laptop or notebook (in English: laptop or notebook) is a mobile or portable personal computer, usually weighs between 1 and 3 kg. Laptop computers are able to perform most of the tasks performed by desktop computers, also called "tower" with similar capacity and with the advantage of reduced weight and size; it also joined with the ability to operate for a specified period without being connected to a power grid.

The word laptop translated into Castilian means: lap (lap) and top (above) that is, a computer that can rest on the legs.

The first laptop was considered as the Epson HX-20 developed in 1981, from which the great benefits for the work of scientists, soldiers, businessmen, and other professionals, who saw the advantage of being able to take with them were observed your computer with all the information they need from one place to another.

The Osborne 1 came to the commercial market in April 1981 in the format currently distinguishes them, but then they were extremely limited, even for the technology of the time.

In 1995, with the arrival of Windows 95, selling laptops it increased significantly, and now exceeds the sales of desktops.

In the third quarter of 2008, sales of laptops for the first time exceeded those of desktop computers, according to research firm
