Certain quantum key distribution achieved by using Bell states
Chong Li, He-Shan Song, Ling Zhou +1
A new protocol for quantum key distribution based on entanglement swapping is presented. In this protocol, both certain key and random key can be generated without any loss of secu…

Alternative new notation for quantum information theory
Chong Li, He-Shan Song, Ling Zhou
A new notation has been introduced for the quantum information theory. By this notation,some calculations became simple in quantum information theory such as quantum swapping, quan…

A random quantum key distribution by using Bell states
Chong Li, He-Shan Song, Ling Zhou +1
We proposed a new scheme for quantum key distribution based on entanglement swapping. By this protocol \QTR{em}{Alice} can securely share a random quantum key with \QTR{em}{Bob}, w…
