In order to overcome the limitation of the prior art quantum key terminal equipment not being able to operate across different segments, the present invention discloses a quantum cryptography service network implementation technique to let a point-to-point quantum key equipment in one segment be redesigned to cooperate with other quantum key equipment in other segments to form a quantum key service network. As opposed to the prior art technique of having each segment generates its own quantum key, the present invention can map one pair of quantum key equipment with another pair of quantum key equipment, or map multiple pairs of quantum key equipment connected in series to have quantum keys entirely or partly shared by the quantum key equipment. Therefore, the generated quantum keys can be used across different segments. Each node in the quantum key service network can provide the quantum key to nearby telecommunication equipment in the telecommunication network of the same premises.
