Abstract

Quantum computers can bring about development in various fields like science and medicine that could save lives. Quantum computing can be instrumental in the advancement of machine learning so that illness can be diagnosed very quickly. With its help materials can be discovered so that efficient structures and devices can be made. It helps to bring about development in financial strategies so that one could lead a better life in retirement. There are various benefits of classical computing that one can experience in day-to-day life. But there are many challenges in today’s world which cannot be solved using classical computing. So quantum computing is developed that can be used to enhance the various algorithms in different fields.

4.1 Introduction

Quantum Computing is the modernization of computing. It is based on quantum mechanics and its phenomena. Quantum computing is the combination of physics, computer science, information theory and mathematics. It provides lower energy consumption, higher computational power and better speed than the classical computers. These can be achieved by controlling how the small objects behave, i.e., microscopic particles like atoms, electrons, photons, etc.
