Scheme for Implementing Controlled Quantum Teleportation in QDs-cavity System

摘要：

In this paper, we propose an experimental scheme for implementing quantum teleportation (QT) of tripartite GHZLike state under the control of the controller. Due to the entanglement produced by the interaction between quantum dots (QDs) embedded in microcavities and a single photons, the controlled quantum teleportation (CQT) scheme of tripartite GHZ-Like state encoded in the electron spins in QDs can be realized via the conditional Faraday rotation of the polarization of single photons, single photons detection and electron spin orientation measurement. By choosing the appropriate Faraday rotation angle for the switchable microcavities, the success probability of CQT can reach 1. The similar CQT procedure discussed here can be generalized to the QT of multipartite GHZ-Like state.
