The strange and counterintuitive principles that define the quantum world, where particles can exist in several states at once and remain connected regardless of the distance between them, present a new foundation for secure communication. Classical communication systems depend on mathematical encryption methods that may eventually be broken by powerful computational technologies. In contrast, this study examines a transformative approach based on the physical laws of quantum mechanics. It focuses on entanglement-based communication channels, where the protection of information is guaranteed by nature rather than by complex algorithms. Through the use of quantum entanglement, two particles can remain linked in such a way that a change in one instantly affects the other, no matter how far apart they are. Any unauthorized attempt to intercept or observe the data disrupts the entangled state, exposing the presence of an intruder. This characteristic ensures a level of security that surpasses traditional cryptographic techniques. Unlike classical encryption, which depends on keys that can eventually be deciphered, entanglement-based systems reveal tampering the moment it occurs. This study represents a crucial step toward the realization of quantum communication networks capable of offering absolute data security. It also lays the groundwork for advancements in information transmission, network design, and the future integration of quantum technologies into global communication infrastructures.
