Controlled teleportation of two atomic state via W state
Zhou Si-fang
Abstract
A scheme for an arbitrary three-particle non-maximally entanglement W state as quantum channel is to achieve the controlled teleporting of two-particle,teleporting unknown quantum state form a sender to either of the two receivers.By the technology of cavity quantum electrodynamics,purifying the non-maximally entanglement state on cavity quantum electrodynamics is purified,the teleportation probability is realized.Transfer with the atoms through the catity resonance interaction to achieve the probability of an unknown quantum state transfer,machinery rather than the conduct of unitary transformation,has greater the feasibility.
