Abstract
A system for use in quantum encryption, decryption, and encoding, comprises a photon production sub-system, a transmission channel sub-system, and a data encoding sub-system. The transmission channel sub-system makes use of the combination of quantum state vectors derived from the photon production sub-system for optical communication with quantum key. The data encoding sub-system includes a plurality of dynamic data encoding modules, and at least one of these modules performs to express the quantum key with bases in an individual Hilbert Space, and divides the transmitting data into segments for data encoding with the individual space bases. In addition to the use in data encoding, the sub-system can also improve the signal-decays and the eavesdropping issue within the quantum channel via implementation of the Laplace Transformation unit and the Quantum Fourier Transformation unit.
