Quantum teleportation represents a significant application form of quantum communication. It is a technology that leverages the distributed quantum entanglement and the conversion of certain physical information to transmit quantum states across arbitrary distances. It constitutes a revolutionary communication mode, characterized by the transmission of not merely classical information but rather the quantum information carried by quantum states. In quantum teleportation, the communicating parties share a pair of entangled particles as the communication channel, enabling the information of an unknown quantum state to be transmitted from the sender to the receiver without physically transferring the particle itself. This technology holds vast potential for application and crucial research value in the fields of quantum information and quantum computation.
