Correlation Measurement of an unknown state with Weak Coupling
Hui Li, Yan-Song Li, Chao Zheng +1
Traditionally, quantum state correlation can be obtained with calculations on a state density matrix already known. Here, we propose a model with which correlations of unknown quan…
The minimal time of dynamic evolution to an arbitrary state
Di Lv, Yan-Song Li, Gui Lu Long
Two bounds on the minimal time of dynamic rotating an initial state by arbitrary angle have been obtained. These bounds have been applied to study the evolutions in the Hadamard-Wa…
Entanglement in a two-identical-particle system
Yan Song Li, Bei Zeng, Xiao Shu Liu +1
The definition of entanglement in identical-particle system is introduced. The separability criterion in two-identical particle system is given. The physical meaning of the definit…
Phase matching in quantum searching
Gui Lu Long, Yan Song Li, Wei Lin Zhang +1
Each iteration in Grover's original quantum search algorithm contains 4 steps: two Hadamard-Walsh transformations and two amplitudes inversions. When the inversion of the marked st…
