Probabilistic teleportation of an arbitrary three-particle state via a partial entangled four-particle state and a partial entangled pair
Hong‐Yi Dai, Cheng-Zu Li, Ping‐Xing Chen · Chinese Physics · 2003
We present a scheme to probabilistically teleport an arbitrary and unknown three-particle state via a two-particle non-maximally entangled state and a four-particle non-maximally entangled state as the quantum channel. With the help of Bell-state measurements, an arbitrary three-particle state can be perfectly teleported if a receiver introduces a collective unitary transformation. All kinds of unitary transformations are given in greater detail. This scheme can be generalized to the teleportation of an arbitrary and unknown multiparticle state.
