Abstract

Semi-quantum communication and cryptography provides a solution to meet the potential threaten caused by quantum computational power in the period of the transition from classical computation to quantum computation, so the algorithms and protocols related with Semi-quantum technology has been become a research hotpot. Though many semi-quantum private comparison protocols were proposed to deal with the privacy protection in data computation in quantum era, most of them have relatively pessimistic efficiency in communication. In our scheme, By using the method of combining two W-like states and identifying the provenance of quantum states, the efficiency of similar semi-quantum privacy comparison is effectively improved. Therefore, the efficiency of this scheme is raised to 7.134% which is doubled compared with previous protocols via this thought of introduce different provenance states. Additionally, the analysis shows that the scheme also features inside and outside security.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
