QDs-Cavity Approach to Controlled Quantum Teleportation of GHZ-Like State
KE-XIANG HU, Bai-Qi Jin, Qingkang Wang · Nano Biomedicine and Engineering · 2010
The experimental scheme for controlled quantum teleportation of tripartite GHZ-like state is presented.With the entanglement generating through the interaction between the quantum dots in microcavities and a single photon, the controlled teleportation can be realized by virtue of Faraday rotation, single photon detection and electron spin orientation measurement.The success probability of the scheme can reach 1 if the cavities are switchable to choice the appropriate Faraday rotation angle.The scheme can be easily generalized to the teleportation of multipartite GHZ-like state.
