Quantum Computing - Basics

The world is moving towards fast and efficient technologies and gadgets. As computers are getting smaller they are getting smarter as well. For a system or technology to become smart, it has to do huge amount of tasks in a fast and efficient manner. That’s where Quantum computing came into existence which is chasing the performance level to make a better history of technology. It implements some properties of Quantum physics for processing of different information. Quantum computing holds the capability to solve some of the toughest problems of all times at a very rapid pace as it operates at a nano-scale level with different components in very high temperatures. Problems (such as modelling complex chemical progression as well as quantum cryptographic algorithms) that will take thousands and billions of years to solve by today’s computing power would take a day or even few hours by quantum computers to solve. Giant firms like Google, IBM and some start-ups are planning to develop the next generation of super computers with the help of quantum computing.

But the quantum computations on every gadgets and technological devices aren’t coming so easily as there’s a lot of gap in the knowledge of how it drives the technology and to what extent it can be solved.

So how Quantum computing works? It uses the Quantum Physics taking benefit of the abilities of subatomic particles to be in more than one state at any specific time interval. With the rapid behaviour of these tiny particles, operations done by them become too quickly consuming less energy as compared to classical computing. While classical computing uses bits to signify one piece of information, quantum computing uses qubits (quantum bits). Bits can be in either in zero or one state called “binary states”, whereas qubits can be in non-trivial correlated states called “entangled states”.

Scientists are successful in building fundamental quantum computers that are capable of doing hard core calculations, but not to the extent quantum computing has the potential of doing; which is still a lot of years to accomplish. It was Mr. Paul Benioff who is recognised as the first computer scientist to apply quantum theory to computers in the year 1981. He also theoretically designed the quantum Turing machine. Moreover, the IBM research division manager of applied quantum computing, Dr. Jerry Chow gave a vivid scenario and possibilities of how quantum computers can be used in molecular simulation which can ultimately contribute to new medicinal compound and material discovery. There are other broader spectrums of technology and science that can be attained using the quantum computing.
