A dynamic group multi-party quantum signature scheme based on extended quantum teleportation that allows for the addition or removal of participants at will, and realizes the dynamic management of group signature permissions and identity authentication by virtue of the state transmission of extended quantum teleportation.
Quantum computation, with tools including Grover’s algorithm, quantum walks, and quantum teleportation, plays an important role in quantum signature designs. Although such designs offer signature functionality, they sometimes come at the cost of security. This paper first reviews a Grover-based scheme and shows how man...

This paper analyzes the four-state QPKE scheme of Liu et al. and shows that its ciphertext structure leaks information about computational-basis plaintexts, and proposes sQPKE, a simple quantum public-key encryption scheme that uses only elementary operations.
