Correlation measures in bipartite states and entanglement irreversibility
Shengjun Wu
We derive quantitative relations among several naturally defined measures of classical and nonclassical correlations in a bipartite quantum state. We also obtain an upper bound of…
Nonexistence of a universal quantum machine to examine the precision of unknown quantum states
Shengshi Pang, Shengjun Wu, Zeng-Bing Chen
In this work, we reveal a new type of impossibility discovered in our recent research which forbids comparing the closeness of multiple unknown quantum states with any non-trivial…
Non-existence of invariant EPR correlation for two qudits, d>2
Shengshi Pang, Shengjun Wu, Marek Zukowski
The two qubit (spin 1/2) singlet state has invariant perfect EPR correlations: if two observers measure {\em any} identical observables the results are always perfectly (anti-)corr…
Quantum measurements with preselection and postselection
Xuanmin Zhu, Yuxiang Zhang, Shengshi Pang +3
We study quantum measurement with preselection and postselection, and derive the precise expressions of the measurement results without any restriction on the coupling strength bet…
Feasible optical weak measurements of complementary observables via a single Hamiltonian
Shengjun Wu, Marek Żukowski
A general formalism for joint weak measurements of a pair of complementary observables is given. The standard process of optical three-wave mixing in a nonlinear crystal (such as i…
