Quantum teleportation transfers an unknown quantum state from one location to another using pre-shared entanglement and classical communication. While not 'teleportation' in the sci-fi sense, it's a fundamental protocol for quantum networking and distributed quantum computing. It's essential for building quantum repeaters and the future quantum internet.
