Since the inception of computer machines, we have made ourselves hugely addicted and dependable to these that today we can’t even think of the technological world without it. We have surrounded our environment with different computing systems, that we cannot move forward a single step without these machines. Today all the technology around ourselves from mechanics to electronics, medics to architecture and other renowned modern fields, all are completely based on computational means. The computers with different diverse units from small to large, general to commercial, desktop to mainframe and further towards super computers all these classes have been heavily indulged in our daily lives in different manners. Though these computing machines have made our lives easy and smooth, they have also enabled us to find different tactical, geographical, medical, economical and mechanical discoveries that has set the stage for future technological world.

But like as the old sayings, everything comes up with two flipping sides, so similar case could be concerned with these fast computing machines. As the number of computer systems continue to emerge and increase in every developed corner of the world because of the increasing necessities and dependability, some of the tech researchers have called this fast pace emergence as the indication to computing power shortage in the near future. According to Semiconductor Industry Association (SIA), a European-American tech research firm has reported that if the silicon based computer systems continued to expand with the same pace and capacity, then by 2040 we will not have the capability to power all of the machines around the globe. And the reason behind this skeptic prediction is very much reasonable.

Like as we all know the modern computer systems are based on transistor based computational boards (motherboards), and these transistors are made of silicon conductors, which requires a sufficient amount of energy to power on and work effectively. Just like in early 60’s when first computer was produced with vacuum tubes as a major component in it, but with the passage of time the scientists replaced those tubes with modern transistors for better energy consumption and computational results. So today in the same way the top computing scientists are now eradicating transistors and talking to move on to something much scientific.

The reason is because millions of computer systems from personal to mainframe around the world are duly based on silicon based transistor boards, and all of them requires some amount of energy to make the world to connect with each other, but because of increasing consumption issues the tech industry is now focused on finding newer ways to make computing more energy efficient, and fast but classical computers are limited by the minimum amount of energy which makes them to perform only one operation at a time.

This is why for the longer term, technologists have raised the questions and have started to work turning classical ways of computing to radically ultra-modern and highly scientific ways of computing, such as Quantum Computing. A computing concept purely based on quantum physics about how states can exist in the form of continuous waves instead of static ones. The idea of Quantum computing is extremely big and it is still in the initial working phase.

What is Quantum Computing:

The massive amount of processing power generated by computer manufacturers has not yet been able to quench our thirst for speed and computing capacity. We have always wanted ‘faster than fast’ speeds to go beyond the normal computational speeds. So the question besides our speed mongering nature is that, will we ever have the amount of computing power we need or want. That is where the concept of Quantum computing comes. Quantum computing takes advantage of the strange ability of ‘subatomic’ particles to exist in more than one state at any time. Due to the way the tiniest of particles behave, operations can be done much more quickly and use less energy than classical computers.

In classical computing, a bit is a single piece of information that can exist in two states 1 or 0. Quantum computing uses quantum bits, or ‘qubits’ instead. These are quantum systems with two states. However, unlike a usual bit, they can store much more information than just 1 or 0, because they can exist in any superposition of these values. So because of it Quantum computers can perform computation 100 times much faster than the normal computers today can.

According to top tech brains, Quantum computers could be the most interesting application in till yet computing history. Because quantum computers would have the capabilities that they could take advantage of odd subatomic interactions to solve certain problems far faster than a conventional machine could. Although a full-scale quantum computer is still years off, scientists have lately made a lot of progress on the materials, designs and methods needed to make one.

While the benefits and opportunities to compute huge chunks of data and information with quantum computers are literally infinite. Quantum computers could simulate how atoms and molecules behave, to the great advantage of chemists and drug designers. They could solve optimization problems like, how to efficiently route airplane traffic far faster than current technology can. They could speed advances in artificial intelligence, improve sensors, and lead to the design of stronger and lighter industrial materials.

Recent Advances in Quantum Computing:

The tech scientists had started to work on quantum computing from a very long time since the inception of modern quantum physics emerged in the field. However any major advancement was lacking because of incomplete thought process about how the subatomic particles could form waves and act together to perform large superposition values. But recently a joint-tech team of Google & Nasa scientists have reached to a major advancement in Quantum computing history, as they have successfully founded a first ever proposed Quantum computer named “D-wave quantum computer” which has the capabilities to perform highly densed computing 100 times faster than a conventional computer can. But still this product is in its testing norms and not produced for any industrial or commercial use because moving quantum computers to an industrial scale is difficult.

So having the present scenario, the practical working on a next generation quantum computers have been started and many countries including tech giants China, US & European nations are investing heavily in it. Because the opportunities with quantum computers are predicted many and is said to be the ‘breaking-barrier’ towards big future discoveries. So it could be best to say that quantum computers would start the new era of thrilling technology that will outburst the ultra-fast computational speeds.
