The roles of quantum correlations in quantum cloning
Jun Zhang, Shao-xiong Wu, Chang-shui Yu
In this paper, we study the entanglement and quantum discord of the output modes in the unified state-dependent cloning and probabilistic quantum cloning. The trip…
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 cost of the weak measurement
Jun Zhang, Shao-xiong Wu, Chang-shui Yu
Quantum correlation cost (QCC) characterizing how much quantum correlation is used in a weak-measurement process is presented based on the trace norm. It is shown that the QCC is r…
