remote information concentration using a bound Entangled State
Physical Review Letters, 2001Co-Authors: Mio Murao, Vlatko VedralAbstract:: Remote information concentration, the reverse process of quantum telecloning, is presented. In this scheme, quantum information originally from a single qubit, but now distributed into three spatially separated qubits, is remotely concentrated back to a single qubit via an initially shared Entangled State without performing any global operations. This Entangled State is a single unlockable bound Entangled State and we analyze its properties.

The squeezing Entangled State of two particles with unequal mass
Chinese Physics B, 2013Co-Authors: Yang Yang, Fan Hong-yiAbstract:For two unequal-mass particles, we construct the Entangled State representation and then derive the corresponding squeezing operator. This squeezing operator has a natural realization in the Entangled State representation, which exhibits the intrinsic relation between squeezing and quantum entanglement. This squeezing operator involves both two-mode squeezing and the direct product of two single-mode squeezings. The maximum squeezing occurs when the two particles possess equal mass. When the two particles' mass difference becomes large, the component of the two single-mode squeezings becomes dominant.

Some New Properties of Wigner Function Studied in Entangled State Representation
Communications in Theoretical Physics, 2010Co-Authors: Fan Hong-yiAbstract:Based on the Wigner operator in the Entangled State representation we study some new important properties of Wigner function for bipartite Entangled systems, such as size of an Entangled State, upper bound of Wigner functions, etc. These discussions demonstrate the beauty and elegance of the Entangled State representation.

On Fermionic Entangled State Representation and Fermionic Entangled Wigner Operator
Communications in Theoretical Physics, 2007Co-Authors: Fan Hong-yiAbstract:By analogy with the bosonic bipartite Entangled State we construct fermionic Entangled State with the Grassmann numbers. The Wigner operator in the fermionic Entangled State representation is introduced, whose marginal distributions are understood in an Entangled way. The technique of integration within an ordered product (IWOP) of Fermi operators is used in our discussion.

Coherent-Entangled State in Three-Mode and Its Applications
Communications in Theoretical Physics, 2006Co-Authors: Fan Hong-yiAbstract:We introduce the new concept of coherent-Entangled State (CES). By virtue of the technique of integration within an ordered product of operators we introduce a new kind of three-mode CES |β,γ,x, which exhibits both properties of the coherent State and the Entangled State. |β,γ,x makes up a new quantum mechancial representation. Its applications in quantum optics are also presented.

A genuine four-partite Entangled State
Physics Letters A, 2008Co-Authors: Ming-yong YeAbstract:In a recent paper, a genuine four-partite Entangled State is proposed [Y. Yeo, W.K. Chua, Phys. Rev. Lett. 96 (2006) 060502], which has been found to have many interesting entanglement properties. We show this State is locally equivalent to some graph States.

faithful remote State preparation using finite classical bits and a nonmaximally Entangled State
Physical Review A, 2004Co-Authors: Ming-yong Ye, Yongsheng ZhangAbstract:We present many ensembles of States that can be remotely prepared by using minimum classical bits from Alice to Bob and their previously shared Entangled State and prove that we have found all the ensembles in two-dimensional case. Furthermore we show that any pure quantum State can be remotely and faithfully prepared by using finite classical bits from Alice to Bob and their previously shared nonmaximally Entangled State though no faithful quantum teleportation protocols can be achieved by using a nonmaximally Entangled State.

Asymmetric Bidirectional Controlled Teleportation by Using Nine-Qubit Entangled State in Noisy Environment
IEEE Access, 2019Co-Authors: Ri-gui Zhou, Ya-nan Zhang, Ruiqing Xu, Chen QianAbstract:In this paper, a novel protocol for asymmetric bidirectional controlled quantum teleportation (ABCQT) by using the nine-qubit Entangled State as a quantum channel is proposed. Alice transmits an arbitrary three-qubit Entangled State to Bob and at the same time, Bob transmits an arbitrary single-qubit Entangled State to Alice under the permission of a third party as a controller. This protocol is based on the Hadamard (H) gates, controlled-not (CNOT) operations, appropriate unitary operations, and single-qubit Von Neumann measurements (SM) which are more efficient than multi-qubit joint measurements (JM). This scheme explicitly shows how the channel of nine-qubit Entangled State prepares, and it is discussed in six types of noisy scenarios (amplitude-damping, phase-damping, bit-flip, phase-flip, bit-phase-flip, and depolarizing noisy scenarios). Then, we analytically derive the fidelities of the ABCQT process and show that they only depend on the amplitude parameter of the initial State and the decoherence noisy rate. Finally, compared with previous schemes, this scheme also shows remarkable advantages.
