In this scheme, two bits of classical information can be encoded on one four-state particle and the transmitted particles can be fully used.展开更多

文摘A measuring-basis encrypted quantum key distribution scheme is proposed by using twelve nonorthogohal states in a four-state system and the measuring-basis encryption technique. In this scheme, two bits of classical information can be encoded on one four-state particle and the transmitted particles can be fully used.
