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…
Stronger uncertainty relations with improvable upper and lower bounds
Jun Zhang, Yang Zhang, Chang-shui Yu
We utilize quantum superposition principle to establish the improvable upper and lower bounds on the stronger uncertainty relation, i.e., the "weighted-like" sum of the variances o…
Optomechanically induced transparency in multi-cavity optomechanical system with and without one two-level atom
Amjad Sohail, Yang Zhang, Jun Zhang +1
We analytically study the optomechanically induced transparency (OMIT) in the -cavity system with the \textit{N}th cavity driven by pump, probing laser fields and the \textit{1}…
Photon statistics on the extreme entanglement
Yang Zhang, Jun Zhang, Chang-shui Yu
The effects of photon bunching and antibunching correspond to the classical and quantum features of the electromagnetic field, respectively. No direct evidence suggests whether the…
