We show the fault-tolerance of the not-so-well known [[8,1,4]] non-CSS code and study the logical error rates of the code. To do so, we adopt the procedure of the bare ancilla method presented by Brown et al. We choose the encoding procedure for stabilizer codes given by Gottesman and modify it to suit the setting of a class of non-CSS codes. We consider two types of noise models for this study, namely the depolarizing noise and anisotropic noise to depict the logical error rates obtained in decoding.
