Complementary measurement-induced quantum uncertainty based on metric adjusted skew information
Bin Chen, Shao-Ming Fei · International Journal of Quantum Information · 2020
We investigate complementary measurement-induced quantum uncertainty based on metric adjusted skew information, and propose two new measures of quantum uncertainty associated with mutually unbiased measurements and general symmetric informationally complete measurements, respectively. Based on these measures of quantum uncertainty, we present two entanglement criteria and show that they detect better entanglement than the existing corresponding criteria by detailed examples.
