Chain teleportation via partially entangled states

Chain teleportation via partially entangled states

We investigate chain teleportation with some nonmaximally entangled channels. The efficiencies of two chain teleportation protocols, the separate chain teleportation protocol (SCTP) and the global chain teleportation protocol (GCTP), are calculated. In SCTP the errors are corrected between every ste...

Zusammenfassung:We investigate chain teleportation with some nonmaximally entangled channels. The efficiencies of two chain teleportation protocols, the separate chain teleportation protocol (SCTP) and the global chain teleportation protocol (GCTP), are calculated. In SCTP the errors are corrected between every step while in GCTP the errors are corrected only at the end. We show that GCTP is more efficient than SCTP.
