The Measurement-Disturbance Relation and the Disturbance Trade-off Relation in Terms of Relative Entropy
Jun Zhang, Yang Zhang, Chang-shui Yu
We employ quantum relative entropy to establish the relation between the measurement uncertainty and its disturbance on a state in the presence (and absence) of quantum memory. For…

Optimal Photon blockade on the maximal atomic coherence
Yang Zhang, Jun Zhang, Chang-shui Yu
There is generally no obvious evidence in any direct relation between photon blockade and atomic coherence. Here instead of only illustrating the photon statistics, we show an inte…

The classical correlation limits the ability of the measurement-induced average coherence
Jun Zhang, Si-ren Yang, Yang Zhang +1
Coherence is the most fundamental quantum feature in quantum mechanics. For a bipartite quantum state, if a measurement is performed on one party, the other party, based on the mea…
