“…In recent techniques, Einstein-PodolskyRosen (EPR) pairs are ideally entangled resources for quantum state sharing [13,14]. For example, Wang et al [15] and Shi et al [11,25,26] have presented several multi-party QSTS schemes for sharing an arbitrary two-qubit state using Bell states as quantum resources. Very recently, several asymmetric schemes for five-party and multi-party quantum state sharing with maximally entangled states of two particles and three particles have been proposed [27][28][29][30].…”

We present a new scheme for investigating the usefulness of non-maximally entangled states for multi-party quantum state sharing in a simple and elegant manner. In our scheme, the sender, Alice shares n various probabilistic channels composed of non-maximally entangled states with n agents in a network. Our protocol involves only Bell-basis measurements, single qubit measurements, and a two-qubit unitary transformation operated by free optional agents. Our scheme is a more convenient realization because no other multipartite joint measurements are needed. Furthermore, in our scheme various probabilistic channels lessen the requirement for quantum channels, which makes it more practical for physical implementation. quantum state sharing, probabilistic channel, multi-particle state, two-particle entangled state Quantum secret sharing (QSS) is a method for creating a private key and dividing it between parties. It has potential applications ranging from quantum secure communication, quantum key distribution, and joint sharing of quantum money [1][2][3][4][5][6]. This research area covers classical secret sharing and quantum information sharing among multiple participants. The latter case was named "quantum state sharing" (QSTS) by Lance et al. [7]. The basic idea of QSTS in the multi-party case is that some information in a secret quantum state of a multi-qubit possessed by one person is distributed between that person, whom we call "Alice", and multiple remote recipients. This is done in such a way that it can be jointly reconstructed and shared only if all participants collaborate. In some sense, QSTS is equivalent to quantum-controlled teleportation. However, during the process of quantum teleportation, an unknown quantum state is transferred to a distant location without revealing any information about the state in the course of the transformation. For a general QSTS protocol, that information is not so restricted. The shared quantum states can be known or unknown in advance to the initial holder. In most QSTS protocols [8][9][10][11][12][13][14][15][16][17][18][19], entanglement is the main phenomenon used to share quantum information. So far, various entangled states have been extensively used in QSTS protocols, such as Bell states [7][8][9][10][11]

“…In 1999, Hillery et al proposed the first QSS protocol [8] for sharing a secret with three-particle and four-particle entangled Greenberger-Horne-Zeilinger (GHZ) states. Up to now, QSS has been extensively studied in both theory and experiments, for instance, in [24][25][26][27] for theory, and in [28][29][30] for experiments. In parallel, the sharing of a quantum state, which is called quantum state sharing (QSTS), has also been developed [29].…”

In this review article, we will review the recent process of quantum communications. In the past decades, there are many developments in quantum communication, for instance, quantum key distribution, quantum teleportation, quantum secure direct communication, deterministic secure quantum communication, quantum secret sharing and so on. And we focus our attention on the recent developments in quantum communication protocols. The principles in quantum mechanics provide novel ways for quantum information transmission and processing, such as quantum computation and quantum communication. In the past decades, quantum information processing has emerged as a promising technology with strategic importance. Because of the peculiar properties of quantum systems, quantum computers possess enormous power that is superior to classical computer. Using quantum computer, factorization of an integer can be accomplished in polynomial time with the Shor algorithm [1]. And we can find a marked item with high probability from an unsorted database with a square-root speedup with the Grover algorithm [2]. In the past decades, the field of quantum information processing and quantum computation have attracted much attention [3][4][5][6]. With these quantum algorithms and a quantum computer, many classical cryptography protocols can be attacked. Thus it is vital to find new cryptographic systems for defending against these attacks.In the following years, there are many branches of quantum communications that are generated which provides us secure ways of communications, such as quantum key distribution (QKD), quantum teleportation, quantum secure direct communication, quantum secret sharing and so on. QKD provides a secure way to distribute secret keys between distant *Corresponding author (email: wangchuan@bupt.edu.cn) users which solves the problem for secure distributing of keys in the classical one-time-pad protocol [7]. However, quantum communication offers more power than QKD. Quantum secret sharing (QSS) distributes secret keys to two or more shared users [8], which can be viewed as the quantum key distribution between multi-users. Quantum teleportation is a basic ingredient in quantum information architectures [9,10]. The principle of quantum teleportation is to transfer an unknown state to the legal user at a distant distance. Quantum secure direct communication (QSDC) offers direct communication of secret messages between distant users, which saves completely the need for another classical communication as in the QKD case. In recent years, there have been considerable developments from researchers in the design of quantum communication protocols. In this article, we will focus on these developments in quantum communications. A brief history and key techniques of quantum communicationQKD provides an unconditional secure way of information exchange between two distant users. The first QKD protocol is proposed by Bennett and Brassard [7], called the BB84 protocol. In 1992, Bennett proposed a simplified version of

Quantum secret sharing as a privacy‐preserving scheme necessitating collaborative efforts from all participating users to collectively recover encrypted information. This paper introduces a novel dynamic multi‐party to multi‐party quantum secret sharing protocol based on Bell states, enabling secure sharing of secrets among dynamically changing multi‐party. The protocol innovatively employs Bell states combined with simplified local unitary operations, significantly reducing the complexity and enhancing the scalability of practical implementations in quantum communication systems. Particularly, through simulation using IBM's Qiskit framework, its correctness and practicality are confirmed. Security analysis demonstrates that the protocol effectively withstands common attack methods, providing reliability, and security in quantum communication. This research presents a more flexible and efficient solution in the field of quantum secret sharing.
