Coherence as uncertainty

Y Sun, S Luo - Physical Review A, 2021 - APS
Coherence of a quantum state (with respect to a fixed incoherent basis) is usually quantified
by distancelike quantities, among which a particularly convenient and intuitive quantifier of …

Quantifying coherence relative to channels via metric-adjusted skew information

Y Sun, N Li, S Luo - Physical Review A, 2022 - APS
In terms of the metric-adjusted skew information (an important and versatile class of
quantum Fisher information), which generalizes the seminal Wigner-Yanase skew …

Skew information-based coherence generating power of quantum channels

Z Wu, L Zhang, SM Fei, J Wang - Quantum Information Processing, 2022 - Springer
We study the ability of a quantum channel to generate quantum coherence when it applies
to incoherent states. We define the measure of coherence generating power (CGP) for a …

Average quantum coherence and its use in probing quantum phase transitions

XY Liu, ML Hu - Physica A: Statistical Mechanics and its Applications, 2023 - Elsevier
We investigate the average quantum coherence (AQC) defined to be the coherence of a
state averaged over all reference bases. This is a basis-independent measure and for any …

Average coherence and entropy

Y Fan, N Li, S Luo - Physical Review A, 2023 - APS
Quantum coherence is one of the characteristic features of quantum mechanics and
underpins many quantum mysteries. To eliminate the influence of the reference basis on the …
