Computers are evolving and growing for the last half a century. They are becoming smaller, faster and powerful but this growth has a limit. A new research has begun which will result in an entirely new kind of computer based on the Quantum physics rules. The quantum computer working on the Quantum physics rules will be able to break the security codes on which our modern computer infrastructure is running. The Quantum computers can solve many problems which are not solvable by the current computer systems. The large scale production of the quantum computers is near, which will result in many opportunities and every field of life will be affected.

Excerpt from the Book
I. INTRODUCTION
This is a long debate that what a quantum computer can do and what they can’t. Quantum computers can simulate the details of biological molecules, can work on intra galaxy research, and can do whatever an ordinary computer can’t. So this type of computer will become an important part of future progress in chemistry, physics, mathematics and engineering. Moreover the quantum computers will open new era of research, development and progress. Experts also see the quantum computers as threat because the computers of this magnitude will break all the cipher codes which are working in our ecommerce and computer systems.
Quantum computer works differently from the traditional computers. The traditional computers can compute only one transaction at a time, it is their speed by which they compute, they seem doing multiple transactions. On the other hand the quantum computers can perform multiple transactions at a time with the speeds more than traditional computers
The fundamental building block of a quantum computer is Qubit as shown in the diagram.
