The quantum theory of optical communications

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 … Light propagating in a restricted volume of space has its energy and momentum quantized according to an integer number of particles known as photons. Quantum optics studies the nature and effects of light as quantized photons. The first major development leading to that understanding was the correct … Visa mer Quantum optics is a branch of atomic, molecular, and optical physics dealing with how individual quanta of light, known as photons, interact with atoms and molecules.
