The purpose of this paper is to present a multi-sensor system with quantum key exchange at the source level and non-binary data transmission at the channel level using the quantum AES algorithm. We differentiate between the classical paradigm based on numerical complexity and the quantum paradigm based on the uncertainty principle. Studies of Bit Error Rate (BER) curves compared a Reed Solomon code with compression and an unencrypted channel are carried out, obtaining a performance of 6 dB and 6.5 dB for a BER of 10-3, respectively. Detection studies are also carried out against the "man-in-the-middle" attack, reaching a probability of approximately 90%.
