Non-classicalities via perturbing local unitary operations
Jun Zhang, Yang Zhang, Shao-xiong Wu +1
We study the nonclassical correlations in a two-qubit state by the perturbing local unitary operation method. We find that the definitions of various non-classicalities including q…

Rényi entropy uncertainty relation for successive projective measurements
Jun Zhang, Yang Zhang, Chang-shui Yu
We investigate the uncertainty principle for two successive projective measurements in terms of Rényi entropy based on a single quantum system. Our results cover a large family of…

Quantum correlation via quantum coherence
Chang-shui Yu, Yang Zhang, Haiqing Zhao
Quantum correlation includes quantum entanglement and quantum discord. Both entanglement and discord have a common necessary condition--------quantum coherence or quantum superposi…
