“…In this scheme, the message owner blinds the message using a key and a hash function, after which quantum bits are prepared for the binary sequence of the blinded message according to dense coding rules. [30][31][32] The message owner utilizes dense encoding and hash functions to blind information, and no one, except the message owner and verifier, knows the content of the original message, effectively protecting the privacy of the message owner. This makes the signature scheme extremely blind.…”

Some schemes where quantum blind signatures require the use of difficult-to-prepare multiparticle entangled states. Considering the communication overhead, quantum operation complexity, verification efficiency and other relevant factors in practical situations, this article proposes a non entangled quantum blind signature scheme based on dense encoding.The information owner utilizes dense encoding and hash functions to blind the information while reducing the use of quantum resources.After receiving particles,the signer encrypts the message using a one-way function and performs a Hadamard gate operation on the selected single photon to generate the signature, and the verifier performs a Hadamard gate inverse operation on the signature and combines it with the encoding rules to restore the message and complete the verification. Compared with some typical quantum blind signature protocols, this protocol has strong blindness in privacy protection, higher flexibility in scalability and application. The signer can adjust the signature operation according to the actual situation, which greatly simplifies the complexity of the signature.Simultaneously utilizing the secondary distribution and rearrangement of non entangled quantum states, a non entangled quantum state representation of three bits of classical information was achieved,reducing the use of a large amount of quantum resources and lowering implementation costs. This improves both signature verification efficiency and communication efficiency, while at the same time, this scheme meets the requirements of unforgeability, non repudiation, and prevention of information leakage.

“…QC includes such areas as quantum teleportation (QT), super-dense coding [1]- [4], quantum secret key distribution [5]- [7] and so on. Among them, the basic principle of QT is to use multi-qubit entangled states as quantum channels and transmit quantum state information with the help of some classical resources.…”

In this paper, a theoretical scheme for bidirectional quantum teleportation by using a four-qubit GHZ state and two Bell states as a quantum channel is proposed. In this scheme, two arbitrary single-qubit quantum states and an unknown three-qubit state can be mutually transmitted between the two communication participants Alice and Bob. The quantum state information can be transmitted if Alice performs four single-qubit measurement operations on her qubits and Bob carries out a four-qubit joint measurement on his qubits, respectively. Then both Alice and Bob can reconstruct the target quantum state by means of appropriate unitary operations. Then we take comparisons with the other bidirectional quantum teleportation protocols in five aspects of quantum information bits transmitted, necessary operations, consumption of quantum resource, consumption of classical resource and intrinsic efficiency. Furthermore, we use channel authentication method to ensure the channel security and prove that our protocol can withstand four attack scenarios. It is concluded that our scheme has significant advantages of more qubits number transmitted, higher intrinsic efficiency and high security. INDEX TERMS Bidirectional quantum teleportation, four-qubit GHZ state and two Bell states, single-qubit measurement, four-qubit joint measurement, channel authentication.
