International audienceThe family of hyperbolic surface codes is one of the rare families of quantum LDPC codes with non-zero rate and unbounded minimum distance. First, we introduce a family of hyperbolic color codes. This produces a new family of quantum LDPC codes with non- zero rate and with minimum distance logarithmic in the blocklength. Second, we show that the parameters [[n, k, d]] of surface codes and color codes satisfy kd^2 ≤ C(log k)^2n, where C is a constant that depends only on the row weight of the parity-check matrix. Our results prove that the best asymptotic minimum distance of LDPC surface codes and color codes with non-zero rate is logarithmic in the length
