Abstract

Based on the standard teleportation scheme and the controlled teleportation scheme for an unknown quantum state of a single two-level particle,it was generalized the discussion to two-particle cases and performed a detailed calculation for the two particle problem.It was discussed briefly the problem of transportation of any unknown quantum state of arbitrary number of two-level particles also.

Probabilistic Teleportation of an Unknown Two-Particle Three-Level Entangled State

Hong‐Yi Dai, Cheng-Zu Li, Ping‐Xing Chen

We propose a scheme to teleport probabilistically an unknown two-particle three-level entangled state by using two partial entangled two-particle three-level states as the quantum channel. This scheme can be directly generalized to teleport an unknown N -particle three-level entangled state by using N partial-entangled two-particle three-level states as the quantum channel.

Use of two-particle entangled states to teleport unknown two-particle quantum state

Zhang Jianzhon

This paper uses a special two-particle entangled state as a quantum channel to achieve invisibility unknown arbitrary two-particle quantum state teleportation. It makes contrast with Yuan, who makes use of χ-type entangled states to achieve two any unknown quantum state teleportation scheme. The scheme uses two sub-channels and Bell-based measurements, as well as special unitary operation successfully completing message teleportation. The program uses fewer resources,and the obtained probability of an original information is 1.

Controlled Teleportation of a Two-Particle Entangled State Through a Cluster State Channel

Song-Song Li

A general scheme for controlled teleportation of an unknown two-qubit entangled state with four-qubit cluster state is proposed.The sender performs a measurement by three particles entangled basis on her own three qubits and the controller needs also take a local measurement.The receiver can reconstruct the unknown state teleported by the sender by performing appropriate unitary operations on his particles if he cooperates with the controller,then the controlled teleportation is accomplished.

Probabilistic Teleportation of an Arbitrary Three-Level Two-Particle State and Classical Communication Cost

Hong‐Yi Dai, Le‐Man Kuang, Cheng-Zu Li

We propose a scheme to probabilistically teleport an unknown arbitrary three-level two-particle state by using two partial entangled two-particle states of three-level as the quantum channel. The classical communication cost required in the ideal probabilistic teleportation process is also calculated. This scheme can be directly generalized to teleport an unknown and arbitrary three-level K -particle state by using K partial entangled two-particle states of three-level as the quantum channel.
