Quantum Teleportation and Quantum Information Splitting by Using a Genuinely Entangled Six-Qubit State

Abstract

A new application of the genuinely entangled six-qubit state introduced recently by Tapiador et al. (J. Phys. A 42:415301, 2009) is investigated for the quantum teleportation of an arbitrary three-qubit state and for quantum information splitting (QIS) of an arbitrary two-qubit state. For QIS, we have shown that it can be completed perfectly with two distinct measurement methods. In our scheme, the joint Bell-state measurement and the joint multi-qubit measurement are needed. This quantum teleportation and QIS schemes are deterministic.

Quantum Teleportation of a Three-qubit State using a Four-qubit Entangled State

“…Thereafter, teleportation of an arbitrary single-qubit state was proposed using tripartite GHZ state [3], four-partite GHZ state [4], SLOCC equivalent W-class state [5], cluster state [6], etc. Teleportation of an arbitrary two-qubit state was proposed using tensor product of two Bell states [7], tensor product of two orthogonal states [8], genuinely entangled five-qubit state [9], five-qubit cluster state [10], six-qubit genuinely entangled state [11], etc.…”

A Resilient Quantum Secret Sharing Scheme

“…Further results related to quantum teleportation, that can be exploited in quantum secret sharing, include results using multipartite quantum channels such as tripartite GHZ state [8], four-partite GHZ state [16], an asymmetric W state [1] and the cluster state [3]. The perfect teleportation of an arbitrary two-qubit state was proposed using quantum channels formed by the tensor product of two Bell states [19], tensor product of two orthogonal states [22], genuinely entangled five qubit state [12], five qubit cluster state [11] and six qubit genuinely entangled states [10]. The idea of Quantum Secret Sharing (QSS) of a single qubit was first due to Hilery et al [7] using three and four qubit GHZ states.…”

Controlled Teleportation of an ECS by Using a Four-Mode CTECS

“…And quantum teleportation schemes are aimed to improve security and capacity of channels upon exploiting the specific features of the involved quantum mechanical systems. Since the first scheme for quantum teleportation was proposed by Bennett et al [1], it has become one of the most important fields of quantum information, and a lot of quantum teleportation and controlled quantum teleportation schemes have been proposed [2][3][4][5][6][7][8]. Subsequently, discrete-variable teleportation has been extended to the cases of continuous-variable corresponding to quantum states of infinite-dimensional spaces [9,10].…”
