The analysis staff, led by Academician GUO Guangcan from College of Science and Know-how of China (USTC) of the Chinese language Academy of Sciences, collaborating with LI Bo from Shangrao Regular College and CHEN Jingling from Nankai College, achieved the masking of optical quantum info. The researchers hid quantum info into non-local quantum entangled states. The research was revealed within the journal Bodily Evaluation Letters.
Quantum info masking as one of many new info processing protocol transfers quantum info from a single quantum service to the quantum entangled state between a number of carriers avoiding the knowledge decode from single quantum service. Not all of the form of quantum states can obtain masking, however the number of that helps individuals to pick out.
The quantum info masking can be utilized in a large scenario, not solely in precise quantum info duties equivalent to quantum secret sharing but additionally the additional understanding within the conservation of quantum info.
On this analysis, the staff realized quantum info masking for the primary time primarily based on the linear optics analysis platform.
In contrast with the theoretical worth, the constancy of the entangled state might be 97.7%, which means that the safe transmission of easy photographs might be full for the three-party quantum secret sharing primarily based on quantum info masking.
This research has nice significance for theoretical analysis and sensible software of safe quantum communication. Based mostly on it, the feasibility of quantum info masking as a brand-new quantum info processing protocol is improved.
