https://en.wikipedia.org/wiki/Quantum_teleportation https://en.wikipedia.org/wiki/Quantum_teleportation > (...) quantum teleportation only transfers quantum information. The sender does not have to know the particular quantum state being transferred nor the location of the recipient, but to complete the quantum teleportation, classical information needs to be sent from sender to receiver. Because classical information needs to be sent, quantum teleportation cannot occur faster than the speed of light. From here it's mind blowing until the part where classical information needs to be sent. Then it only seems useful as a way to transfer quantum state safely and undetected. It's really cool that the classical information can be broadcasted, so you can keep the recipient's location secret. Maybe quantum cryptographic keys, if that's a thing, can be sent this way, or a channel that just teleports quantum data without a chance of of being overheard can be setup.
