Quantum teleportation relies on the phenomenon of quantum entanglement, which allows the instantaneous transfer of quantum states between widely separated particles, allowing information, such as qubits, to be "teleported" from one location to another without the particle itself being transported. This process, called quantum teleportation, is crucial for the development of quantum communications and communication networks that can ensure inviolable information security. Future applications of quantum teleportation may include secure data transmission channels, quantum computer networks, and new applications of quantum technology.
