Plots of quantum coherence for different partitions C_q₁q₂ (dash line), C_c₁c₂ (dot line), C_q₁c2 = C_q₂c1 (dash–dot line), C_q₁c₁ (dash–dot–dot line) versus gt with ϕ = π/6. Solid line denotes the coherence invariant of C_q₁q₂ + C_c₁c₂, panels (a) and (b) show the purity of initial states r = 1, and panels (c) and (d) display the purity of initial states r = 0.6.
