This entire paragraph is just breaking my mind. Need to find an quantum entanglement for dummies book or something
>“By performing a destructive measurement on two photons — one carrying a quantum state and one entangled with another photon — the quantum state is transferred onto the remaining photon, which can be very far away,” said Jordan Thomas, a Ph.D. candidate in Kumar’s laboratory and the paper’s first author. “The photon itself does not have to be sent over long distances, but its state still ends up encoded onto the distant photon. Teleportation allows the exchange of information over great distances without requiring the information itself to travel that distance.”

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.
