Nowadays computers work on bits that survive as either 0 or 1. Quantum computers aren’t restricted to two states; they encode data as quantum bits, or qubits, which can survive in superposition. Qubits identify atoms, ions, photons or electrons and their various standard devices that are running collectively to act as computer memory and a processor.

In the view of a quantum computer, we can identify that a quantum computer can control these multiple states at the same time, it has the possibility to be billions of times much stronger than present most strong supercomputers.

A CPU that can use memory device of qubits will be capable to carry out calculations using all the manageable values of the input registers at the same time. This superposition reasoning a phenomenon known as quantum parallelism, and is the motivating power backside the research state carried out in quantum computing.


The main object of quantum computing is to discover algorithms that are well quicker than classical algorithms finding the same as problem. In this article we will talk about need of quantum computation and the advantages they offer us in compare with the classical computers.

We will also discuss what the elements of Quantum computing are. Along with this we will talk about the challenges to Quantum computing. In this article we will conduct a simulation experiment using IBM D-WAVE Quantum computers.
