TL;DR: In this article, an one-way quantum identity authentication scheme is proposed by employing mechanism of ping-pong protocol and property of quantum controlled-NOT gate. But the proposed scheme is not secure under general individual attack.

TL;DR: It is shown that the quantum block cryptographic algorithm, in which the key can be reused after undergoing a check procedure, can prevent quantum attack strategy as well as classical attack strategy.
Abstract: Based on quantum computation, a novel quantum block cryptographic algorithm that can be used to encrypt classical messages is proposed. The security of this algorithm is analyzed from several aspects. It is shown that the quantum block cryptographic algorithm, in which the key can be reused after undergoing a check procedure, can prevent quantum attack strategy as well as classical attack strategy. The problem of key management is discussed and the circuits for encryption and decryption are suggested.

TL;DR: Pereira et al. as mentioned in this paper improved the quantum key distribution protocol by employing the second-order coherence of optical fields, which can be easy experimentally measured with a Hanbury-Brown and Twiss intensity interferometer.

TL;DR: In this article, a cascade quantum teleportation scheme based on entanglement swapping is presented and compared with the cascade quantum multi-teleportation scheme, which can effectively teleport quantum information and extend the distance of quantum communication.
Abstract: In this letter a cascade quantum teleportation scheme is proposed. The proposed scheme needs less local quantum operations than those of quantum multi-teleportation. A quantum teleportation scheme based on entanglement swapping is presented and compared with the cascade quantum teleportation scheme. Those two schemes can effectively teleport quantum information and extend the distance of quantum communication.
