Teleportation is a new and exciting field of future communication. Working in this field requires knowledge of Entanglement, Quantum Computation, Quantum Mechanics and Mathematics. This book covers the short review of these fields and has filtered out the necessary components for teleportation. In this book, teleportation concept, its process, road blocks, and successes that have been achieved recently have been presented in a straightforward and innovative manner. By separating unique features of teleportation this book has showed that it is going to be used practically for quantum key distribution in very near future. At the end the book has discussed on quantum key distribution methods and concepts. These will work as a guideline for designing quantum key distribution system using entanglement and teleportation.
