Fig.7 (Color online) For Bell-diagonal state $c_{1}=0.3, c_{2}=-0.4, c_{3}=0.56$:(a) Relative entropy of coherence under the bit-flip channel and phase-flip channel $n=10$ times (Cbf-pf). (b) Relative entropy of coherence under the bit-flip channel and bit-phase-flip channel $n=10$ times (Cbf-bpf) (c) Relative entropy of coherence under the phase-flip channel and bit-phase-flip channel $n=10$ times (Cpf-bpf).
