Axially Symmetric Hermite-Gaussian Beams and the BB84 Protocol for the Space-Earth Quantum Cryptography Channel
Axially Symmetric Hermite-Gaussian Beams and the BB84 Protocol for the Space-Earth Quantum Cryptography Channel
DOI: 10.22184/1993-7296.FRos.2023.17.7.542.555
The paper provides a description of Hermite-Gaussian beams with an axially symmetric polarization structure generated by a vector superposition of Hermite-Gaussian modes with the indices 10 and 01. It is shown that the axial polarization symmetry makes such beams insensitive to the rotations relative to the optical axis that makes such a modification of the well-known BB84 protocol preferred for the quantum space cryptography systems. The possible creation and detection of such beams within the framework of a polarization protocol transmission using the devices with a radial polarizer is discussed.
