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

Most of the quantum authentication protocols are used to authenticate quantum messages. In this paper, by using a pair of non-entangled qubits, a quantum authentication protocol of classical messages is proposed. In the pair of qubits, the first one is used to carry a bit message, and the second one is used as a tag to authenticate the classical message. In our protocol, a bit string instead of a sequence of maximally entangled states is used directly as an authentication key, so the authentication key can be easily stored offline. On the other hand, in our protocol, a unitary operation UA is chosen to encrypt the qubits so that the successful probability of all attacks analyzed is less than one. Our quantum authentication protocol is secure against various attacks such as the no-message attack and message attacks.
