Introduction to the World of Quantum Computers

The world is changing very fast, and so are the ways of communication and computation. This article is about a new communication and information technology based on the principles of the quantum physics. At first we discuss about some fundamental paradigms of Quantum Computers World, and then introducing the basis of quantum computation: "QBit". After that we explain some magic properties of this atomic QBit including quantum measurement, superposition, entanglement, etc. Then we introduce quantum gates the basic modules of the next generation computers, their relation with the ordinary logical gates and the properties of some of the most useful quantum gates. And finally, we have a brief talk on some magic algorithm and the relation between these new born creatures and other fields of computers world, based on the quantum theories and manipulated by the quantum circuits
