Fig.2 (Color online) Relative entropy of coherence for Bell-diagonal state $c_{1}=0.3$, $c_{2}=-0.4$, and $c_{3}=0.56$: (a)under bit flip channel $n$ times, (b) under phase flip channel $n$ times,(c) under bit-phase flip channel $n$ times, (d) under depolarizing channel $n$ times,(e) under generalized amplitude damping channel $$ times, (f) under amplitude damping channel $n$ times.
