Pictorial representation of a teleportation protocol. Description of a teleportation protocol. The two stations A and B share an entangled state and a classical communication channel (dashed black line), which is used to communicate the result i of the Bell state measurement (BSM) performed in A in order to drive a unitary operation $U_i$. The initial quantum state ${\left|\Psi \right.〉}_T$, which is physically present in A, is thus teleported in B.
