Concepts Of Quantum Computing

Quantum computing is based upon physics completely different from that observed in the electronic devices of today. In today's computing paradigm, a transistor can be in only one of two states called bits - 0 or 1, on or off. But in the realm of quantum computing a transistor can be in a state of 0, 1, or a "superposition" of 0 or 1. And there can be many superpositions. These quantum bits are called "qubits." Physically, qubits are encoded in atoms, photons, ions, or electrons.

Whereas a standard transistor can perform only one operation at a time, a qubit can perform many simultaneously. Therefore a quantum computer containing the same number of transistors as an ordinary computer of today can be a million times faster. A 30-qubit quantum computer could perform as many as 10 teraflops - 10 trillion floating-point operations per second! Today's desktop computers perform gigaflops - billions of operations per second.

So obviously, that's where the interest in quantum computing comes from - speed. A personal computer a million times faster than the one currently on your desk boggles the mind. After all, how fast can you type? But there are applications that would benefit from that type of speed, such as image recognition, cryptography, and other problems that require enormous computing power. Personally, I'd be happy with a computer that's ready to go as soon as you turn it on. I don't anticipate being able to type a million times faster than I already do.

One problem with quantum computing is that if you observe the quantum state of a qubit, it changes. So scientists must devise an indirect method of determining the state of a qubit. To do this, they are trying to take advantage of another quantum property called "entanglement." At the quantum level, if you apply a force to two particles they become "entangled;" a change in the state of one particle is instantly reflected in the other particle's change to the opposite state. So by observing the state of the second particle, physicists hope to determine the state of the first.

Know something about WIMAX technology

WiMAX Technology is also one of the emerging wireless technology that provide us high speed mobile data and telecommunication services. WiMAX stands for Worldwide Interoperability for Microwave Access and it is based on IEEE 802.16 standards.In this technological world, we have so many technologies that help us in every aspect of our daily life such as transportation, communication etc. Wimax Technology works same as Wi-Fi does but it is more improved and efficient then WiFi and it can route data to Wi-Fi that is Wi-Fi devices can take advantage of WiMAX connection. WiMAX technology providess higher speed connection up to 70 Mbps over the area of 30 miles. There is no need for line of sight connection between subscriber terminals and the base station in WiMAX technology and it can support hundreds if not thousands of subscribers from a single base station. It is also specified in 802.16 standards that it will supports low latency applications such as voice, video, and Internet access at the same time. To Read about What is WiMAX technology

What is SURFACE COMPUTING?

Surface computing at its most basic is an attempt to make the use of a computer better match the way we interact with other things in our environments as well as better interacting with those things and allowing for far less time thinking about how we interact with our computers so more energy can be put into how we use them.

The most common and popular type of surface computing is that of touch screen monitors of the type that can be found on many modern phones. These are also common in many businesses where untrained workers are expected to use a computer. Until recently though these touch screen monitors were really little more than a replacement of the mouse. You could still only point at one thing at a time, and it wasn't even as good as a mouse because you can't right click or highlight things without using a keyboard.

More recently though both Microsoft and Apple have come up with new ways to use surface computing.

Microsoft's plan is a device called Microsoft Surface which takes the form of a large table and would be used in places such as hotels and casinos or board rooms. The key difference between this and other similar devices is the multi touch system. This allows users to use both hands to manipulate things such as photos, as well as the use of hand gestures and even physical gestures. Other features on the Microsoft surface allows for wireless communicates between devices so things like phones, cameras and laptops can sync with the table and move data between them effortlessly.

Huawei launches Android phones

Telecom equipment manufacturer Huawei said its subsidiary Huawei Devices has launched Android-based smartphone, IDEOS, at a price of Rs 8,499 in the country.


The smartphone offers multiple ways to access the Internet and comes pre-loaded with a range of social networking, email and useful services like Google Talk, Google Maps, YouTube and GMail, the company said in a statement.


Android is a software for mobile devices that includes an operating system, middleware and key applications.


"Innovation and premium experiences shouldn't be restricted to high-priced devices. We believe that IDEOS will redefine the Internet experience for Indian youth," Huawei Devices Marketing Director Anand Narang said.

An Android™ phone can also run multiple applications at the same time and in the background of a phone, making multitasking easier and the functionality of the phone more fluid than other cellphones.
Android™ phones are considered revolutionary in some circles because of its open source, mobile platform. All developers, whether professional or hobbyists, are encouraged to write programs and applications for the Android™ operating system and contribute to the evolving Android™ project by submitting them to the Android™ Market. G1 users then choose to download and use the applications on their phone by accessing the application library on their handset.

What is ANDROID PHONES ?

An Android™ phone is a cellphone that uses the Google-developed Android™ operating system and platform. Google partnered with the High Tech Computer Corporation (HTCC) to build hardware for the G1 cellphone, the first mobile phone to run the Android™ platform. In 2008, T-Mobile premiered the G1 Android™ phone to the public.
On the technical side, an Android™ phone runs on the Android™ operating system, key applications and middleware. It's Linux kernel-based, has applications that are written in the Java language and can even run applications written in the C language. It is also a product, partly, of the Open Handset Alliance, which encourages the use and advancement of open source software for cellphones.
