Minimal evolution time (red solid line) of the same model and its different QSL bounds (black lines) as a function of γ₀.

The bounds are derived from the previous result¹⁶ (dotted), Eq. (4) (solid) and Eq. (5) (dashed). Also indicated here is the degree of non-Markovianity²⁴ (blue solid line). We set λ = 1 and τ = 10.
