Basics of Entanglement in Communication
Utilizing entanglement in communication systems enables the encoding and transmission of quantum information with improved security and efficiency. Quantum information refers to information that is stored in quantum systems, utilizing quantum properties such as superposition and entanglement.
Communication protocols are essential in transmitting this quantum information reliably and securely.
Entanglement, a phenomenon where two or more particles become correlated in such a way that the state of one particle is dependent on the state of the other(s), plays a vital role in quantum communication. By harnessing entanglement, quantum communication protocols can achieve tasks that are impossible with classical systems.
For instance, quantum key distribution protocols utilize entanglement to establish secure communication channels that are protected from eavesdropping through the principles of quantum mechanics.
