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.
