A Brief Survey on Quantum Computers

Priyanshi Kotlia, Janmejay Pant

Abstract: Since last years, computers reduce the human efforts and give improvement in its performance day by day. Quantum computers are those computers who perform computing which is based on the phenomenon called Quantum Mechanics. It is a fusion of classical computing which we were using now days, physics and mathematics. And the computing they performed by integrating these fields is termed as Quantum Computing. Quantum computers perform their computing on the basis of the microscopic particles like ions, photons, electrons, protons, neutrons etc which ultimately give exponentially high computation power and other advantages too like less consumption of electricity which we will discuss in the same paper in brief over the classical computers, which we were using till day. In this paper we will briefly explain the quantum computers, its history, its properties in which its computing is based upon, its advantages& disadvantages, its limitation, its real world application, the difference between classical computers and Quantum computers and the challenges it faced and at last we conclude it with its future scope.

Keywords: Quantum computing, real time application, properties, future scope, Teleportation
