By using a partially entangled two-particle state and a partially entangled three-particle W state as the quantum channel,a scheme for probabilistic teleportation of an arbitrary two-particle state is presented.The total maximal probaaility equals 2/3.
We present a scheme for teleporting an arbitrary and unknown two-particle state from a sender to either one of two receivers. The quantum channel is composed of two non-maximally three-particle entangled W states. An arbitrary two-particle state can be perfectly teleported probabilistically if both the sender performs two generalized Bell-state measurements and either one of two receivers adopts an appropriate unitary transformation, conditioned on the suitable measurement outcomes of the other receiver and classical information.
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.
A scheme for teleporting an arbitrary and unknown three-particle state from a sender to either one of two receivers is proposed. The quantum channel is composed of a two-particle non-maximally entangled state and two three-particle non-maximally entangled W states. An arbitrary three-particle state can be perfectly teleported probabilistically if the sender performs three generalized Bell-state measurements and sends to the two receivers the classical result of these measurements and either one of the two receivers adopts an appropriate unitary transformation conditioned on the suitable measurement outcomes of the other receiver.
