The Next Generation Computing Brainwave-Quantum Computing

T. Venkat Narayana Rao, Shirish Pathania


This paper is written to explicate the working of Quantum Computing and its mechanics. Quantum Computing is basically a minute
field from Nanotechnology. The main purpose of this paper is to explain an inexperienced user about the technology and principles used while
designing the architect of a quantum computer.Operational quantum computers would be a reality in forth coming years by the virtue of new
mechanisms to explore and implementations.This paper is sectioned into 7 parts. Part 1 is a brief introduction to Quantum Computing i.e. basic
working principle of a Qubit. Part 2 covers Qubit and the architect of the whole system. It also enlightens us about the Qubit in more detail like
how data is represented, principles like superposition and state of composite system. Part 3 narrates how quantum Computing can be built using
Qubits and applies the above mentioned principles. Part 4 deals with the basic introduction to Quantum Mechanics and some principles like dual
nature of light and Uncertainty Principle. Part 5 depicts about the advantages of Quantum Computer over present computing systems. Part 6
discusses the overheads of Quantum Computing. Part 7 describes about implementation of Quantum Computing in today’s world. Finally this
paper offers an insight about how and by when we would be able to design a full time Quantum Computer and what are the probable
considerations to be taken in to account.
