More Information
Summary:A scheme, in which cross-Kerr nonlinearity is used for the Bell-state measurements and preparation of the resource of entanglement, is proposed for teleporting an entangled 2-photon state by using two polarization-photon Bell states as quantum channel based on cross-Kerr nonlinearity combined with linear optics elements such as polarization beam splitters and half wave plates. Teleportation of the entangled 2-photon polarization state can realized with certainty in principle. ► This is a very simple scheme for teleportation based on cross-Kerr nonlinearity. ► The cross-Kerr medium is used for “measuring” and “distinguishing” Bell states. ► Successful probability and fidelity for teleportation both reach theoretically 1.
