From: Witness of non-Markovian dynamics based on Bhattacharyya quantum distance
Comparison between the qualitative behaviors of the Bhattacharyya distance (\(D_{Bhatt}\)), the Bures distance (\(D_{Bures}\)), Hilbert-Schmidt speed (\(HSS_{\phi 1}\)), and quantum Fisher information (\(\mathcal {F}_{\phi 1}\)) with respect to the phase of the fields in terms of scaled time for the three-level atom scenario when \(\Omega _{R1}=0.3, \Omega _{R2}=1, \omega _a=0.9,\omega _b=\omega _c=1, \varphi =\phi _1=\phi _2=\psi =\pi\) and \(\theta =\pi /4\).
