Quantum Computing

Abstract

Over time and increasing of power Computers are getting smaller and smaller. There is more crunching capability in today phones compared with room sized computer developed 5 decades ago. although of these continuous improvement, many complex problems still unsolved even with the most powerful computers. One critical problem is computer's memory and switching unit (transistor) that have achieved a level where they will be just an atom. This rise the necessity of powerful possibilities of quantum computing that have millions times faster processors than the used ones in classical computers. quantum computing still more complexed than classical computing and based on quantum physics where classical physics laws don't apply. This work gives a brief overview about quantum basics, detailed analysis and comparison between classical computers and quantum computers, bene ts, disadvantages and future prospects
