Multiple teleportation via the partially entangled states

TL;DR

This paper compares two protocols for multiple quantum teleportation using partially entangled states, demonstrating that the global protocol outperforms the separate one in efficiency.

Contribution

It introduces and analyzes the efficiencies of SMTP and GMTP, showing GMTP's superiority in multiple teleportation scenarios with nonmaximally entangled channels.

Findings

GMTP is more efficient than SMTP

Efficiency depends on the entanglement quality of channels

Quantitative comparison of protocols

Abstract

We investigate the multiple teleportation with some nonmaximally entangled channels. The efficiencies of two multiple teleportation protocols, the separate multiple teleportation protocol (SMTP) and the global multiple teleportation protocol (GMTP), are calculated. We show that GMTP is more efficient than SMTP.
