Example Concept: Quantum teleportation relies on entangling a pair of qubits, one at the sender's location and one at the receiver's. The sender performs a Bell-state measurement on their qubit and the qubit to be teleported, collapsing the system into one of four possible states. The result is sent via classical communication to the receiver, who applies a corresponding quantum gate to their qubit, recreating the original quantum state. This process allows for the secure and efficient transfer of quantum information without the need for a direct quantum channel.
