“…With the rapid development of quantum information technology in recent decades, quantum entanglement has begun to play a very critical role as a physical resource. Many quantum information protocols have been developed based on quantum mechanics principles, including quantum key distribution [1,2], quantum secure direct communication [3,4], quantum teleportation (QT) [5,6], and quantum private comparison [7][8][9]. Especially in QT, the preparer can transfer an unknown quantum state to a remote receiver using classical information and quantum resources.…”

A scheme for the deterministic joint remote preparation of a fourqubit cluster-type state using only two Greenberger-Horne-Zeilinger (GHZ) states as quantum channels is presented. In this scheme, the first sender performs a two-qubit projective measurement according to the real coefficient of the desired state. Then, the other sender utilizes the measurement result and the complex coefficient to perform another projective measurement. To obtain the desired state, the receiver applies appropriate unitary operations to his/her own two qubits and two CNOT operations to the two ancillary ones. Most interestingly, our scheme can achieve unit success probability, i.e., P suc =1. Furthermore, comparison reveals that the efficiency is higher than that of most other analogous schemes.

“…In general, QDC can be divided into two categories: quantum secure direct communication (QSDC) [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] and deterministic secure quantum communication (DSQC). [27][28][29][30][31][32][33][34][35] The difference between QSDC and DSQC is that there are some classical bits communicated to assist the receiver to decrypt the secret in DSQC, while in QSDC there is not. Quantum broadcast communication (QBC) [36][37][38] as a special kind of QDC was put forward several years ago, which involves a sender and multiple receivers.…”

The security of quantum broadcast communication (QBC) and authentication protocol based on Greenberger-Horne-Zeilinger (GHZ) state and quantum one-time pad is analyzed. It is shown that there are some security issues in this protocol. Firstly, an external eavesdropper can take the intercept-measure-resend attack strategy to eavesdrop on 0.369 bit of every bit of the identity string of each receiver without being detected. Meanwhile, 0.524 bit of every bit of the secret message can be eavesdropped on without being detected. Secondly, an inner receiver can take the intercept-measure-resend attack strategy to eavesdrop on half of the identity string of the other's definitely without being checked. In addition, an alternative attack called the CNOT-operation attack is discussed. As for the multi-party QBC protocol, the attack efficiency increases with the increase of the number of users. Finally, the QBC protocol is improved to a secure one.

In this study, a novel multiparty quantum sealed-bid auction protocol using the single photons as the message carrier of bids is proposed, followed by an example of three-party auction. Compared with those protocols based on the entangled states (GHZ state, EPR pairs, etc.), the present protocol is more economic and feasible within present technology. In order to guarantee the security and the fairness of the auction, the decoy photon checking technique and an improved post-confirmation mechanism with EPR pairs are introduced respectively.Keywords Multiparty quantum sealed-bid auction · single photons · decoy photon checking technique · post-confirmation 1 IntroductionDue to the principles of quantum mechanics, such as no-cloning theorem, uncertainty principle, and entanglement characteristics, quantum system shows a lot of advantages than classic ones.
