Operation triggered quantum clock synchronization
Jie-Dong Yue, Yu-Ran Zhang, Heng Fan
We present a novel quantum clock synchronization(QCS) scheme of multiple parties which uses operation as the trigger to start the evolution of the initial state, where existing QCS…
Demonstration of Entanglement-Enhanced Phase Estimation in Solid
Gang-Qin Liu, Yu-Ran Zhang, Yan-Chun Chang +3
Precise parameter estimation plays a central role in science and technology. The statistical error in estimation can be decreased by repeating measurement, leading to that the resu…
Multipartite distribution property of one way discord beyond measurement
Si-Yuan Liu, Yu-Ran Zhang, Wen-Li Yang +1
We investigate the distribution property of one way discord in multipartite system by introducing the concept of polygamy deficit for one way discord. The difference between one wa…
Global quantum discord and quantum phase transition in XY model
Si-Yuan Liu, Yu-Ran Zhang, Wen-Li Yang +1
We study the relationship between the behavior of global quantum correlations and quantum phase transitions in XY model. We find that the two kinds of phase transitions in the stud…
Quantum Metrological Bounds for Vector Parameter
Yu-Ran Zhang, Heng Fan
Precise measurement is crucial to science and technology. However, the rule of nature imposes various restrictions on the precision that can be achieved depending on specific metho…
