Optimizing incompatible triple quantum measurements
Hui-Hui Qin, Shao-Ming Fei
We investigate the optimal approximation to triple incompatible quantum measurements within the framework of statistical distance and joint measurability. According to the lower bo…
Characterizing multipartite entanglement by violation of CHSH inequalities
Ming Li, Huihui Qin, Chengjie Zhang +3
Entanglement of high-dimensional and multipartite quantum systems offer promising perspectives in quantum information processing. However, the characterization and measure of such…
Quantifying Algebraic Asymmetry of Hamiltonian Systems
Hui-Hui Qin, Shao-Ming Fei, Chang-Pu Sun
The symmetries play important roles in physical systems. We study the symmetries of a Hamiltonian system by investigating the asymmetry of the Hamiltonian with respect to certain a…
Uncertainties of genuinely incompatible triple measurements based on statistical distance
Hui-Hui Qin, Ting-Gui Zhang, Leonardo Jost +3
We investigate the measurement uncertainties of a triple of positive operator-valued measures (POVMs) based on statistical distance, and formulate state-independent tight uncertain…
