Splet15. nov. 2024 · The goal of this work is to investigate the spectrum-estimation-based method in three directions: First, we generalize the spectrum-estimation-based method to detect the geometric measure of coherence, which has not been investigated yet. SpletThe linear entropy used to measure coherence loss due to the stochastic dephasing is discussed. With analysis, we find that the time evolution of entanglement and the linear entropy depends not only on the structure of states of concern, but also on the strength of the fluctuations of the random variable in the stochastic process.

SpletWe can compare the result with the trace distance measure of coherence, C Tr (ρ) = min σ ∈ Δ 1 2 ∥ ρ − σ ∥ 1, introduced in : C Tr (ρ) ≤ C max (ρ) ≤ 2 C Tr (ρ).
