Generation of multiphoton Greenberger–Horne–Zeilinger state and its two kinds of teleportation

Abstract

We propose a comprehensive experimental scheme to generate and teleport GHZ states of any number of photons as well as to accomplish the process of open-destination teleportation of a single photon's arbitrary state. The equipment and techniques which are used in our scheme are all feasible under current technology. Moreover, we make a direct extension of the above cases and investigate the open-destination teleportation of any M-photon general GHZ states with a brief diagram.

GENERATION OF MULTIPHOTON POLARIZATION-ENTANGLED CLUSTER STATES AND THE CORRESPONDING OPEN-DESTINATION TELEPORTATION

Di Chang, Yong-Chang Huang

We propose a method to generate multiphoton polarization-entangled cluster states of any number photons by using the fusion operations of two-photon cluster states and a kind of local operation, and then analyze the process of open-destination teleportation of a single photon state using the generated states. Apart from theoretical deductions, we also give the experimentally schematic diagram, which requires only BBOs, Polarization Beam Splitters, half-wave plates, single photon resources as well as some other linear optical elements. The equipment and techniques used here are all feasible under current technology.

Spin-orbit-path hybrid Greenberger-Horne-Zeilinger entanglement and open-destination teleportation with multiple degrees of freedom

Lixiang Chen, Weilong She

We propose a scheme to generate hybrid Greenberger-Horne-Zeilinger (GHZ) entanglement where multiple photons are entangled in different degrees of freedom of spin, orbital angular momentum (OAM), and path (linear momentum). The generation involves mapping the preliminary OAM entanglement of photon pairs onto their spin-orbit and spin-path degrees of freedom, respectively. Based on the hybrid GHZ entanglement, we demonstrate an open-destination teleportation with multiples degrees of freedom, via which a spin state of a single photon is teleported onto a superposition of multiple photons with the postselection technique and the original information could be read out at any photon in individual spin, OAM, or the linear-momentum state. Our scheme holds promise for asymmetric optical quantum network.

Teleportation of an n -bit one-photon and vacuum entangled GHZ cavity-field state

Lai Zhen-jiang, Fan Feng-Guo, Zhu Gang-Yi +1 more

A scheme for teleporting an arbitrary n -bit one-photon and vacuum entangled Greenberger–Horne–Zeilinger (GHZ) state is proposed. In this scheme, the maximum entanglement GHZ state is used as a quantum channel. We find a method of distinguishing four Bell states just by detecting the atomic states three times, which is irrelevant to the qubit number of the state to be teleported.

Controlled Teleportation of an Arbitrary Multi-Qudit State in a General Form with d -Dimensional Greenberger–Horne–Zeilinger States

Xihan Li, Deng Fu-Guo, Hong-Yu Zhou

A general scheme for controlled teleportation of an arbitrary multi-qudit state with d -dimensional Greenberger–Horne–Zeilinger (GHZ) states is proposed. For an arbitrary m -qudit state, the sender Alice performs m generalized Bell-state projective measurements on her 2 m qudits and the controllers need only take some single-particle measurements. The receiver Charlie can reconstruct the unknown m -qudit state by performing some single-qudit unitary operations on her particles if she cooperates with all the controllers. As the quantum channel is a sequence of maximally entangled GHZ states, the intrinsic efficiency for qudits in this scheme approaches 100% in principle.

Generating Greenberger-Horne-Zeilinger states using multiport splitters

Daniel Bhatti, Stefanie Barz

Symmetric multiport splitters are versatile tools in optical quantum information processing. They can be used for studying multiparticle scattering, for studying distinguishability and mixedness, and also for the generation of multipartite entangled quantum states. Here, we show that $N$-photon $N$-mode Greenberger-Horne-Zeilinger (GHZ) states can be generated using symmetric multiport beam splitters. Varying the input states' internal degrees of freedom and postselecting onto certain photon-number distributions allows the probabilistic generation of GHZ states with arbitrary photon numbers. We present two schemes, one for odd and one for even numbers of photons, to generate GHZ states using symmetric multiport splitters and compare them to a strategy utilizing a $2N$-port network as well as the standard postselection method.

Generation of an arbitrary concatenated Greenberger–Horne–Zeilinger state with single photons

Shan‐Shan Chen, Lan Zhou, Yu‐Bo Sheng

Abstract The concatenated Greenberger–Horne–Zeilinger (C-GHZ) state is a new kind of logic-qubit entangled state, which may have extensive applications in future quantum communication. In this letter, we propose a protocol for constructing an arbitrary C-GHZ state with single photons. We exploit the cross-Kerr nonlinearity for this purpose. This protocol has some advantages over previous protocols. First, it only requires two kinds of cross-Kerr nonlinearities to generate single phase shifts ± θ . Second, it is not necessary to use sophisticated m -photon Toffoli gates. Third, this protocol is deterministic and can be used to generate an arbitrary C-GHZ state. This protocol may be useful in future quantum information processing based on the C-GHZ state.
