Scientists Achieve On-Demand Quantum Teleportation For The First Time
View attachment 617
Generically, teleportation protocols proceed by three steps (Fig. 1): a pair of quantum systems in an entangled state is produced and distributed, one to a sender (Alice) and the other to a receiver (Bob); Alice makes a joint measurement of her member of the entangled pair and the unknown state she wishes to teleport, and sends the measurement result to Bob; Bob uses the measurement result he receives from Alice to manipulate his quantum system in a predetermined way. After this manipulation, Bob's quantum system ends up being in the unknown state, that teleported from Alice to Bob, with the only direct communication being a classical message — Alice's measurement result...
