Quantum speed-up transition in open system dynamics
Xiang Hao, Wenjiong Wu
The rate of the trace distance is used to evaluate quantum speed-up for arbitrary mixed states. Compared with some present methods, the approach based on trace distance can provide…

Nonunital non-Markovian dynamics induced by a spin bath and interplay of quantum Fisher information
Xiang Hao, Wenjiong Wu, Shiqun Zhu
We explore the nonunital non-Markovian dynamics of a qubit immersed in a spin bath. The nonunital environmental effects on the precisions of quantum parameter estimation are invest…
