A new scheme for probabilistic teleportation and its potential applications

TL;DR

This paper introduces a new probabilistic teleportation scheme that requires only the sender to know the entangled state, potentially enhancing security and applicability in quantum communication.

Contribution

It presents a novel teleportation method that relaxes the receiver's knowledge requirement of the entangled state, expanding the practical use of probabilistic quantum teleportation.

Findings

The scheme allows teleportation with only the sender knowing the entangled state.

Potential applications improve security in quantum communication.

The method broadens the range of scenarios for probabilistic teleportation.

Abstract

We propose a novel scheme for probabilistic teleportation when the information of the partially entangled state is only available for the sender. This is in contrast with the fact that the receiver must know the non-maximally entangled state in previous typical schemes for the teleportation. Additionally, we illustrate two potential applications of the novel scheme to probabilistically teleport an unknown two-level quantum state from a sender to a receiver with the help of an assistant, who plays distinguishable roles under different communication conditions, and the applications indicate that our proposal could improve the security and enlarge the applied range of probabilistic teleportation.
