Leggett-Garg inequalities for multitime processes
Zhiqiang Huang, Xiao-Kan Guo
We study some aspects of the Leggett-Garg inequalities by using the operator-state formalism for multitime processes. The process tensor in its Choi-state form, which we call proce…
On the relation between quantum Darwinism and approximate quantum Markovianity
Xiao-Kan Guo, Zhiqiang Huang
There are strong evidences in the literature that quantum non-Markovianity would hinder the presence of Quantum Darwinism. In this Letter, we study the relation between quantum Dar…
Classical and quantum parts of conditional mutual information for open quantum systems
Zhiqiang Huang, Xiao-Kan Guo
We study the classical, classical-quantum, and quantum parts of conditional mutual information in the ``system-environment-ancilla'' setting of open quantum systems. We perform the…
Fluctuation Theorems for multitime processes
Zhiqiang Huang
In this paper, we extend the fluctuation theorems used for quantum channels to multitime processes. The fluctuation theorems for quantum channels are less restrictive. We show that…
