Quantum state transmission over q-CDMA network.
(a) The broom-shaped or shovel-shaped purple symbols denote photon detectors. The red arrow inside each (green) cavity denotes the classical driving field with amplitude Ωi(t) (i = 1, 2, 3, 4). The green circles denote Λ-type three-level atoms. (b) Schematic diagram of the chaotic synchronization realized by the moving mirrors. (c) Chaotic encoding and decoding by electro-optic modulators.
