Abstract

A scheme of quantum direct communication using non-symmetric quantum channel superdense coding is proposed.In this scheme,the server prepares the initial states in two nonorthogonal basis sets which forbids any one to copy them perfectly,so the scheme is more secure.This scheme also has a higher capacity than other schemes,for using the ideas in non-symmetric quantum channel superdense coding.

Quantum Communication Scheme Using Non-symmetric Quantum Channel

Hai-Jing Cao, Zhong-Hua Chen, He‐Shan Song

A theoretical quantum communication scheme based on entanglement swapping and superdense coding is proposed with a 3-dimensional Bell state and 2-dimensional Bell state function as quantum channel. quantum key distribution and quantum secure direct communication can be simultaneously accomplished in the scheme. The scheme is secure and has high source capacity. At last, we generalize the quantum communication scheme to d-dimensional quantum channel.

Quantum secure direct communication network with superdense coding and decoy photons

Fu‐Guo Deng, Xihan Li, Chunyan Li +2 more

A quantum secure direct communication network scheme is proposed with quantum superdense coding and decoy photons. The servers on a passive optical network prepare and measure the quantum signal, i.e. a sequence of the d -dimensional Bell states. After confirming the security of the photons received from the receiver, the sender codes his secret message on them directly. For preventing a dishonest server from eavesdropping, some decoy photons prepared by measuring one photon in the Bell states are used to replace some original photons. One of the users on the network can communicate to any other one. This scheme has the advantage of high capacity, and it is more convenient than others as only a sequence of photons is transmitted in quantum line.

Quantum Secure Communication by Using GHZ State in High-Dimensional Hilbert Space

Gan Gao

We propose a quantum superdense coding secure communication scheme by using GHZ state. This scheme combines the ideas of quantum superdense coding and sequence transmission. Its distinct advantage is high source capacity. In addition, in checking eavesdropping, we need not to destroy quantum entanglement.

Quantum Secure Direct Intercommunication with Superdense Coding

Ying Guo, Moon Ho Lee

A quantum secure direct intercommunication scheme is proposed to exchange directly the communicators' secret messages by making use of swapping entanglement of Bell states. It has great capacity to distribute the secret messages since these messages have been imposed on high-dimensional Bell states via the local unitary operations with superdense coding. The security is ensured by the secure transmission of the travel sequences and the application of entanglement swapping.
