We present a scheme for asymmetric quantum-information splitting, where a sender
distributes asymmetrically a quantum secret (quantum state) to distant partners in a network …

We propose a scheme for multiparty hierarchical quantum-information splitting (QIS) with a
multipartite entangled state, where a boss distributes a secret quantum state to two grades of …

In this paper, a quantum private comparison protocol is proposed based on χ-type state.
According to the protocol, two parties can determine the equality of their information with the …

We propose a generation scheme of χ-type entangled states based on weak cross-Kerr
nonlinearities. After Homodyne measurement, the individual photons can be entangled …

Employing a polarization-entangled χ χ state, which is a four-photon genuine entangled
state, we propose a protocol teleporting a general two-photon polarization state. Firstly, the …

Simple schemes are proposed for implementing deterministic teleportation, superdense
coding, and quantum information splitting with W-type entangled states. The physical …

Based on the genuine four-particle entangled state (Yeo and Chua in Phys. Rev. Lett. 96:
060502, 2006) and the ping-pong protocol (Boström and Felbinger in Phys. Rev. Lett. 89 …

Two schemes via different entangled resources as the quantum channel are proposed to
realize remote preparation of an arbitrary four-particle χ χ-state with high success …

The research of multi-particle entanglement is a hot topic because of its important
applications and far-reaching effects on vast aspects of quantum information. The article is …

A multiuser quantum direct communication network system for N users utilizing χ-type
entangled states is proposed. The network system is composed of a communication center …
