Controlled Teleportation of a Three-Qubit State by Using a Five-Qubit Cluster State
International Journal of Theoretical Physics, 2020Co-Authors: Yi Qiao, Ming-huang Sang, Yi-you NieAbstract:We propose a scheme of controlled teleportation of an arbitrary three-Qubit State by using a five-Qubit cluster State. In our scheme, the sender Alice performs five sets of single-Qubit measurements and the controller Charlie needs only take a single-Qubit measurement. The receiver Bob can reconstruct the arbitrary three-Qubit State by performing the single-Qubit unitary operations and a controlled-NOT operation if he obtains the help of the controller. We show that the efficiency in this scheme approaches 100%

quantum information splitting of an arbitrary three Qubit State by using a genuinely entangled five Qubit State and a bell State
Quantum Information Processing, 2012Co-Authors: Yi-you Nie, Jun-chang Liu, Ming-huang SangAbstract:A new application of the genuinely entangled five-Qubit State introduced by Brown et al. (J Phys A 38(5), 1119---1131, 2005) is investigated for quantum information splitting (QIS) of an arbitrary three-Qubit State. We demonstrate that such a genuine five-Qubit entangled State and a Bell-State can be used to realize the deterministic QIS of an arbitrary three-Qubit State by performing the Bell-State measurements and single Qubit measurement. The presented protocol is showed to be secure against certain eavesdropping attacks.

quantum information splitting of an arbitrary three Qubit State by using two four Qubit cluster States
Quantum Information Processing, 2011Co-Authors: Yi-you Nie, Jun-chang Liu, Ming-huang SangAbstract:A new application of the four-Qubit cluster State is investigated for quantum information splitting (QIS) of an arbitrary three-Qubit State. Muralidharan and Panigrahi (Phys Rev A 78:062333, 2008) argued that a four-Qubit cluster State is impossible for QIS of an arbitrary two-Qubit State. In this paper, we demonstrate that two four-Qubit cluster States can be used to realize the deterministic QIS of an arbitrary three-Qubit State by performing only the Bell-State measurements. Our scheme considered here is secure against certain eavesdropping attacks.

Optimal reconstruction of a pure Qubit State with local measurements
arXiv: Quantum Physics, 2003Co-Authors: Emilio Bagan, Mukarram Baig, Alex Monras, Ramon Muñoz-tapiaAbstract:We analyse the reconstruction of an unknown pure Qubit State. We derive the optimal guess that can be inferred from any set of measurements on N identical copies of the system with the fidelity as a figure of merit. We study in detail the estimation process with individual von Neumann measurements and demonstrate that they are very competitive as compared to (complicated) collective measurements. We compute the expressions of the fidelity for large $N$ and show that individual measurement schemes can perform optimally in the asymptotic regime.

Optimal scheme for estimating a pure Qubit State via local measurements.
Physical review letters, 2002Co-Authors: Emilio Bagan, Mukarram Baig, Ramon Muñoz-tapiaAbstract:We present the optimal scheme for estimating a pure Qubit State by means of local measurements on N identical copies. We give explicit examples for low N. For large N, we show that the fidelity saturates the collective measurement bound up to order 1/N. When the signal State lays on a meridian of the Bloch sphere, we show that this can be achieved without classical communication.

quantum State sharing of an arbitrary three Qubit State by using four sets of w class States
Optics Communications, 2011Co-Authors: Yi-you Nie, Jun-chang Liu, Ming-huang SangAbstract:A new application of the W-class State for quantum State sharing (QSTS) of an arbitrary three-Qubit State with a certain probability is presented explicitly. We show that three sets of W-class States can be used to realize the QSTS of an arbitrary three-Qubit State involving Bell-State measurement, single-Qubit measurement and one high dimensional unitary operation. The performance demonstrates that our scheme can considerably reduce the difficulty of physical implementation.

Controlled Teleportation of an Arbitrary Three-Qubit State by Using a Genuinely Entangled Six-Qubit State and a Bell-State
International Journal of Theoretical Physics, 2010Co-Authors: Yi-you Nie, Jun-chang Liu, Ming-huang SangAbstract:A new application of the genuinely entangled six-Qubit State introduced recently by Borras et al. [J. Phys. A 40:13407, 2007] is investigated for the controlled teleportation of an arbitrary three-Qubit State. In our scheme, a genuinely entangled six-Qubit State and a Bell-State are shared by a sender (Alice), a controller (Charlie) and a receiver (Bob). Both the sender and the controller only need to perform Bell-State measurements (BSMs), the receiver can reconstruct the arbitrary three-Qubit State by performing some appropriate unitary transformations on his Qubits after he knows the measured results of both the sender and the controller. This controlled teleportation scheme is deterministic.

an efficient scheme for five party quantum State sharing of an arbitrary m Qubit State using multiQubit cluster States
Quantum Information Processing, 2011Co-Authors: Kui Hou, Guohong Liu, Xueyong Zhang, Shouqi ShengAbstract:We present an efficient scheme for five-party quantum State sharing (QSTS) of an arbitrary m-Qubit State with multiQubit cluster States. Unlike the three-partite QSTS schemes using the same quantum channel [Phys. Rev. A 78, 062333 (2008)], our scheme for sharing of quantum information among five parties utilizing a cluster State as an entangled resource. It is found that the six-partite cluster State can be used for QSTS of an entangled State, the five-partite cluster State can be used for QSTS of an arbitrary two-Qubit State and also can be used for QSTS of an arbitrary m-Qubit State. It involves two-Qubit Bell-basis or three-Qubit GHZ-basis measurements, not multipartite joint measurements, which makes it more convenient than some previous schemes. In addition, the total efficiency really approaches the maximal value.
