This chapter proposes two practical application schemes: noise-resistant quantum dialogue and continuous variable quantum key distribution. The former utilizes decoherent-free subspaces and super-entangled states to construct a quantum dialogue protocol capable of achieving secure communication in collective noise environments. The latter improves the security and efficiency of the protocol through decoy state and steganography techniques. Furthermore, the chapter puts forward a continuous variable quantum key distribution protocol that leverages quantum entanglement and decoy state techniques to ensure the security of key distribution. These applications underscore the immense potential of quantum steganography in the domain of information security and delineate novel avenues for prospective practical applications of quantum communication technology.

摘要

This chapter proposes two practical application schemes: noise-resistant quantum dialogue and continuous variable quantum key distribution. The former utilizes decoherent-free subspaces and super-entangled states to construct a quantum dialogue protocol capable of achieving secure communication in collective noise environments. The latter improves the security and efficiency of the protocol through decoy state and steganography techniques. Furthermore, the chapter puts forward a continuous variable quantum key distribution protocol that leverages quantum entanglement and decoy state techniques to ensure the security of key distribution. These applications underscore the immense potential of quantum steganography in the domain of information security and delineate novel avenues for prospective practical applications of quantum communication technology.
