Quantum Information Theory for Quantum Communication

F. Stef Roux

Sándor Imre, László Gyöngyösi

The book provides an overview of the most advanced quantum informational geometric techniques, which can help quantum communication theorists analyze quantum channels, such as security or additivity properties. Each section addresses an area of major research of quantum information theory and quantum communication networks. The authors present the fundamental theoretical results of quantum information theory, while also presenting the details of advanced quantum ccommunication protocols with clear mathematical and information theoretical background. This book bridges the gap between quantum physics, quantum information theory, and practical engineering.

Measurement is a very important object of quantum information and quantum computation theory, and an important tool for obtaining quantum information.The development of quantum measurement theory not only plays a very important role in the field of quantum theory, but also gradually penetrates into other inter-disciplines.This thesis introduces the theory of quantum measurement and communication, explores the features of quantum teleportation and privacy communication, and addresses the issue of quantum de-coherence in the process of measurement, which can offer some beneficial enlightenment to us in acquiring a further understanding of the theory of quantum communication.

This chapter discusses quantum mechanics and certain quantum computing elements are initially. Errors are introduced in quantum computation because a quantum system cannot be completely isolated from its environment. The chapter explores certain quantum algorithms. It aims to develop a formal model of quantum computation via quantum Turing machine. The chapter outlines preliminaries for stating the laws of quantum mechanics. It aanlyses the strengths and drawbacks of the quantum computing paradigm. Quantum communication channels, encoders, and decoders are some of the examples of superoperators. One of the important concepts in quantum computation and communication is that of quantum entanglement. Analogously quantum information theory addresses the problem of optimal communication over a quantum channel. Information theory is the study of communication systems from a probabilistic point of view. Analogous to classical communication theory, quantum communication theory studies the limits of efficient data storage and transmission of quantum information. Quantum cryptography uses the principles of quantum mechanics.
