A quantum computer is akin to a classical computer in multiple ways. Analogous to a conventional computer, the information could be stored in some physical system. One needs to invoke the system, perform some sort of operations possibly by means of running a program, and extract the information. Nevertheless, simply told, quantum computing differs from classical computing in two key succinct elements. Firstly, quantum computers can acquire a well defined quantum state, but subjected to random behavior this is the idea of superposition. Secondly, the random behavior goes in a correlated manner – this is the idea of entanglement. Of course, these ideas are the hall mark of quantum computing counterintuitive though. At a very intricate level, conventional computers are mired in digital logical circuits dealing with long strings of 0’s and 1’s. While quantum computing runs on quantum bits aptly called QBITS. Qbits need not have to be binary during computations; they can actually exit in well defined combinations of 0s and 1s. This review paper has intuitive intents that are more than one; to provide an exposition of the topic to an interested novice, to explore possible applications of quantum computing, to delineate the prospective stake holders once quantum computing heralds new vistas, to throw the light on this topic in terms of possible disruptions that may happen in foreseeable future, and to emphasize the impacts of quantum computing.
