Teleportation and secret sharing with pure entangled states

Somshubhro Bandyopadhyay

We present two optimal methods of teleporting an unknown qubit using any pure entangled state. We also discuss how such methods can also have successful application in quantum secret sharing with pure multipartite entangled states.

Optimal Conclusive Teleportation of an Arbitrary d -Dimensional N -Particle Unknown State via a Partially Entangled Quantum Channel

Hao San-Ru, Hou Bo-Yu, Xiao-Qiang Xi +1 more

In this paper we generalize the standard teleportation to the conclusive teleportation case which can teleport an arbitrary d-dimensional N-particle unknown state via the partially entangled quantum channel. We show that only if the quantum channel satisfies a constraint condition can the most general d-dimensional N-particle unknown state be perfect conclusively teleported. We also present a method for optimal conclusively teleportation of the N-particle states and for constructing the joint POVM which can discern the quantum states on the sender's (Alice's) side. Two typical examples are given so that one can see how our method works.

Optimal conclusive teleportation of a d -dimensional two-particle unknown quantum state

Yu‐Guang Yang, Wen Qiao-yan, Fu-Chen Zhu

A conclusive teleportation protocol of a d -dimensional two-particle unknown quantum state using three d -dimensional particles in an arbitrary pure state is proposed. A sender teleports the unknown state conclusively to a receiver by using the positive operator valued measure(POVM) and introducing an ancillary qudit to perform the generalized Bell basis measurement. We calculate the optimal teleportation fidelity. We also discuss and analyse the reason why the information on the teleported state is lost in the course of the protocol.
