A New Scheme for Probabilistic Teleportation and Its Potential Applications

Abstract

We propose a novel scheme to probabilistically teleport an unknown two-level quantum state 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 for probabilistic teleportation from a sender to a receiver with the help of an assistant, who plays distinct roles under different communication conditions, and our results show that the novel proposal could enlarge the applied range of probabilistic teleportation.

Probabilistic Teleportation via Quantum Channel with Partial Information

Desheng Liu, Zhiping Huang, Xiaojun Guo

Two novel schemes are proposed to teleport an unknown two-level quantum state probabilistically when the sender and the receiver only have partial information about the quantum channel, respectively. This is distinct from the fact that either the sender or the receiver has entire information about the quantum channel in previous schemes for probabilistic teleportation. Theoretical analysis proves that these schemes are straightforward, efficient and cost-saving. The concrete realization procedures of our schemes are presented in detail, and the result shows that our proposals could extend the application range of probabilistic teleportation.

Quantum controlled teleportation when only the sender knows the partially entangled state

Jiahua Wei, Tingting Zhang, Wei Guo +3 more

In this paper, a new proposal was presented to probabilistically transmit an unknown quantum state from a sender to a remote receiver with the aid of a controller when the non-maximally entangled state is only available for the sender. Meanwhile, the whole successful probability and classical communication of this scheme for controlled teleportation are calculated. The concrete processes of our proposal are elaborated in detail. This scheme would be used to expand the research range of quantum controlled teleportation.

Probabilistic Teleportation via a Partially Entangled GHZ State being Known by only the Sender

Li Xin Xia, Run Qin Liu, Wei Min Zheng

In some typical schemes, the receivers must know the information of a non-maximally entangled state for quantum teleportation. In this paper, using a generalized measurement, we propose a scheme of probabilistic teleportation via a quantum GHZ-entangled state, which is known by only the sender.

A Better Controlled Scheme of Probabilistically Teleporting an Unknown 3D two Particle Entangled State for the Receiver

Zha Xin-wei

We establish a scheme for probabilistically teleporting an unknown 3D(dimensional) two-particle state using non-maximally entangled states as a quantum channel.In this scheme,the probabilistic teleportation is realized by using the new orthogonal complete bases measurement instead of the traditional Bell measurement,and we also use 3D entangled state as the quantum channel.These are different from the previous schemes.This scheme is more convenient for the receiver,because users could realize communication with less operators.

Teleportation of an unknown bipartite state via non-maximally entangled two-particle state

Hai-Jing Cao, Yanqing Guo, He‐Shan Song

In this paper a new scheme for teleporting an unknown entangled state of two particles is proposed. To weaken the requirement for the quantum channel, without loss of generality, two communicators only share a non-maximally entangled two-particle state. Teleportation can be probabilistically realized if sender performs Bell-state measurements and Hadamard transformation and receiver introduces two auxiliary particles, operates C -not operation, single-qubit measurements and appropriate unitary transformations. The probability of successful teleportation is determined by the smaller one among the coefficients' absolute values of the quantum channel.
