Dynamics of skew information-based quantum coherence under correlated noisy channels
Guoyou Wang, You-neng Guo, Zhi‐Hong Deng · Journal of Modern Optics · 2022
In this paper, we study analytically the skew information-based coherence, and compare its dynamics with that of the l1 norm of coherence for two-qubit Bell-diagonal states under the influence of correlated Pauli channels, such as correlated dephase, depolarizing and classical noisy channels, respectively. The similar as well as different features between the skew information-based coherence and l1 norm of coherence are discussed. In addition, the physical mechanism of preserving quantum coherence based on memory coefficient of correlated channels and non-Markovian memory effect is also expounded.
