Introduction -- Vector and Hilbert Spaces -- Elements of Quantum Mechanics -- Elements of Quantum Mechanics -- Quantum Decision Theory -- Quantum Telecommunications Systems -- Quantum Telecommunications Systems with Thermal Noise -- Implementation of Quantum Telecommunications Systems -- Quantum Information with Continuous States -- Quantum Information with Discrete States.

This book demonstrates that a quantum communication system using the coherent light of a laser can achieve performance orders of magnitude superior to classical optical communications Quantum Communications provides the Masters and PhD signals or communications student with a complete basics-to-applications course in using the principles of quantum mechanics to provide cutting-edge telecommunications. Assuming only knowledge of elementary probability, complex analysis and optics, the book guides its reader through the fundamentals of vector and Hilbert spaces and the necessary quantum-mechanical ideas, simply formulated in four postulates.
