Quantum speed limit for a mixed initial state
Shao-xiong Wu, Chang-shui Yu
A unified bound on the quantum speed limit is obtained for open quantum systems with the mixed initial state by utilizing the function of relative purity proposed in [Phys. Rev. Le…

Local quantum uncertainty guarantees the measurement precision for two coupled two-level systems in non-Markovian environment
Shao-xiong Wu, Yang Zhang, Chang-shui Yu
Quantum Fisher information (QFI) is an important feature for the precision of quantum parameter estimation based on the quantum Cramér-Rao inequality. When the quantum state satisf…
