“…When compared with current CDSQC protocols, which have two transmissions of the same quantum signals (i.e., first from the controller to the sender, and then from the sender to the receiver), the protocol developed by Wang et al [12] exhibits higher qubit efficiency. Hence, in this subsection, we compare the qubit efficiency of the protocol developed by Wang et al with that of our proposed scheme.…”

In this study, we propose a controlled deterministic secure quantum communication (CDSQC) protocol based on the idea of Grover's quantum search algorithm (QSA). The proposed protocol has the following two advantages over the existing CDSQC protocols: (1) high qubit frequency and (2) less quantum memory. Moreover, the security analysis of the proposed protocol shows that any eavesdropper will be detected with a very high probability under both ideal and noisy quantum channel conditions.

“…There is a review article about QSDC in [11], which gave a detailed account of QSDC and DSQC. After that, a number of quantum secure direct communication protocols were presented, such as the protocols using single particle [12][13][14], in fact, [12] is just the deterministic QKD protocol in [15] with single photons, EPR pairs [16][17][18][19][20][21][22], GHZ state [23][24][25][26][27], W state [28] and four-qubit χ -type entangled state [29,30], two-photon three-qubit cluster state [31], hyperentanglement [32][33][34][35], and others interesting QSDC protocols [36][37][38][39][40].…”

In a quantum secure direct communication protocol, two remote parties can transmit the secret message directly without first generating a key to encrypt them. A quantum secure direct communication protocol using two-photon four-qubit cluster states is presented. The presented scheme can achieve a higher efficiency in transmission and source capacity compared with the proposed quantum secure direct communication protocols with cluster states, and the security of the protocol is also discussed.

“…The communication is secure under some eavesdropping attacks and that two users can transmit their secret message securely. Wang et al [12] have presented a multiparty CQSDC protocol using GHZ state. This communication protocol can be used to transmit three bits of secret message and the secret message can only be recovered by the receiver under the permission of all the controllers.…”

We present a controlled quantum secure direct communication protocol by using cluster states via swapping quantum entanglement and local unitary operation. In the present scheme, the sender transmit the secret message to the receiver directly and the secret message can only be recovered by the receiver under the permission of the controller.Keywords Controlled secure direct communication · Cluster state · Entanglement swappingQuantum key distribution (QKD) is probably one of the most promising concepts in quantum information theory, in which two remote legitimate users (Alice and Bob) establish a shared secret key through the transmission of quantum signals and use this key to encrypt (decrypt) the secret messages. Since Bennett and Brassard presented the pioneer QKD protocol in 1984 [1], a lot of QKD protocols have been advanced [2][3][4][5][6]. Recently, a novel branch of quantum communication, quantum secure direct communication (QSDC) has been proposed and actively pursued [7-10]. Different from QKD whose object is to generate a private key between two remote parties, QSDC can transmit the secret messages directly without creating a key to encrypt them beforehand.Beige et al. [7] have proposed that messages can be read out only after the transmission of an additional piece of classical information for each qubit. Boströem et al. [8] have proposed a quasi-secure ping-pong QSDC protocol. Deng et al. [9] have proposed a two-step quantum direct communication protocol using Einstein-Podolsky-Rosen (EPR) pair, which attracted a great deal of attention. Wang et al.[10] proposed a protocol for quantum secure direct communication with cluster states, which is easily processed by a one-way quantum computer. Recently, Xia et al. [11] have present a controlled quantum secure direct communication
