Is the conditional entropy squeezing indicts the normalized entropic uncertainty relations steering?
A novel approach is introduced to assess one-way Normalized Entropic
Uncertainty Relations (NEUR)-steering in a two-qubit system by utilizing an
average of conditional entropy squeezing. The mathematical expressions of
conditional entropy squeezing and NEUR-steering are derived and presented. To
gain a better understanding of the relationship between the two measures, a
comparative analysis is conducted on a set of two-qubit states. Our results
reveal that the two measures exhibit complete similarity when applied to a
maximally entangled state, while they display comparable behavior with minor
deviations for partially entangled states. Additionally, it is observed that
the two measures are proportionally affected by some quantum processes such as
acceleration, noisy channels, and swapping. As a result, the average of
conditional entropy squeezing proves to be an effective indicator of
NEUR-steering.Comment: 8 pages, 5 figures. All comments are welcom
