What is Quantum Computing


Computers we use for everyday's work use transistors, and its computational power depends upon the no of transistors it contains. Gordon Moore noticed that the number of transistors per square inch on integrated circuits had doubled every year since their invention. Moore's law predicts that this trend will continue occur in near future. But Moore's law is going to fail in near future as there is a limit the number of transistors we can fit in the given chip.

As the technology is growing, the thrust of increased processing power is snowballing and since Moore's law is going to fail in near future, we need alternate way to fulfill the hunger. If this trend continues to be followed then by 2040 we will not have the capability to power all of the machines around the globe. Thus the industry is focused on finding ways to make computing more energy efficient, but classical computers are limited by the minimum amount of energy it takes them to perform one operation. So to fulfill our requirement we need to reach to subatomic particles to find a way where operations can be done much more quickly using less energy than classical computers.

A bit is single piece of information that can only exist in two states: 1 or 0. Quantum computer uses quantum bits also known as 'qubits'. These quantum systems exist in two states. These can store much more information than just 1 or 0, as they values can exist in any superposition. If the qubit is in a superposition of the 1 state and the 0 state, and it performed a calculation with another qubit in the same superposition, then one calculation actually obtains 4 results: a 1/1 result, a 1/0 result, a 0/1 result, and a 0/0 result.

This is due to the result of mathematics applied on quantum system while in a state of de-coherence, which lasts when it is in superposition of states until it collapses down into one state. The exact physical mechanism at work within the quantum computer is somewhat theoretically complex and intuitively disturbing.

Thus Quantum Computers are next generation computers and are amazingly fast. Last year team of Google and NASA scientists found a D-wave quantum computer which is 100 million times faster than a conventional computer. But moving quantum computing to an industrial scale is difficult.

Android Pie: Cool features you shouldn't overlook

In this era of technical growth companies have been trying to improve user experience by making device usability better and handy. As mobile phone are being introduced with various new technologies for eg. face recognition which uses AI to enhance the user experience, similarly many other inventions are being worked on at present and support those new features the OS needs to be upgraded to match their pace with the development of technology. Or it may also be said that with advancement in the OS versions the Mobile companies need to be design the phone to cop its level.
Android 9 controls the power of artificial intelligence to provide more from the smart phone. Now it's smarter, faster and adapts with usage.

What is Deep Learning - Explained in General Terms

Deep Learning, Machine Learning and Artificial Intelligence are the terms which are being used interchangeably these days. Suddenly every one is talking about them – irrespective of whether they understand the differences or not! Whether one have been actively following data science or not – everyone would have heard these terms. But no one has a clear understanding of what is Deep Learning. Basically it is subset of Machine Learning which in turn is subset of Artificial Intelligence.

Deep Learning is type of Machine Learning which teaches computers to perform actions by learning from examples. Deep Learning is the key technology being used in Driver-less cars that enables them to recognize a stop sign and differentiate between a person and lamppost.It is the key behind the voice controls in various devices like phone, tablets, TVs and hands-free speakers. Deep Learning is gradually prevailing and getting attention lately. Using it, impossible results have been achieved.

In deep lear…

Chromecast: All you need to know

Digital media player, Chromecast is a small dongle developed by Google for accessing playbacks from mobile device or computers on high definition TVs. The device controls/initiate the playback of internet streamed audio and visual content on TVs through mobile or web Apps. The device supports Google cast for mirroring of content on HD TV's.

Google Cast SDK is a third party modification software which was released on 3rd Feb, 2014. Third party Apps can use google cast for enabling their apps to be accessible through Chromecast on high definition Tvs. After the release, 20,000 google cast ready apps were sold till May 2015. 30 million units of Chromecast are sold till now in US making it the best seller streaming device in US in 2014.

There are three Chromecast device launched till now:
1. Chromecast 1st Generation
2. Chromecast 2nd Generation
3. Chromecast 3rd Generation


Chromecast 1st Generation
It is the first Chromecast device announced on July 24,2013 and was made av…
