The quantum theory of optical communications
Webb28 nov. 1990 · Quantum communication theory is receiving much attention as the basis for practical optical communications and quantum measurements. This book is a unique survey of the activities of the leading research groups from mathematical physics, information theory, and various areas in quantum optics. WebbThe orthogonality of optical states of a given beam wavelength and direction, but with different orbital angular momentum values, certainly affords extensive opportunities for quantum communication: the enhanced encoding of information per photon in a high-dimensionality transverse structure is, however, subject to both fundamental quantum …
