Entangling power of two-qubit gates on mixed states
Zhe Guan, Huan He, Yong-Jian Han +3
The ability to reach a maximally entangled state from a separable one through the use of a two-qubit unitary operator is analyzed for mixed states. This extension from the known ca…
Universal Optimal Gates Regarding Quantum Entanglement and Discord Generating
Zhe Guan, Huan He, Yong-Jian Han +2
Fernando Galve \emph{et al.} introduced discording power for a two-qubit unitary gate to evaluate its capability to produce quantum…
Experimental test of the tradeoff relation in weak measurement
Geng Chen, Yang Zou, Xiao-Ye Xu +9
An upper bound between the information gain and state reversibility of weak measurement was first developed by Y. K. Cheong and S. W. Lee [Phys. Rev. Lett. 109, 150402 (2012)]. The…
Quantitative verification of the Kibble-Zurek mechanism in quantum non-equilibrium dynamics
Xiao-Ye Xu, Yong-Jian Han, Kai Sun +4
The Kibble-Zurek mechanism (KZM) captures the key physics in the non-equilibrium dynamics of second-order phase transitions, and accurately predict the density of the topological d…
