  • Making use of the advantage of classical Low Density Parity Check (LDPC) codes based on Balance Incomplete Block Designs (BIBD), a novel construction of quantum LDPC codes is proposed in this paper. The constructed check matrix satisfies the requirement of self-dual quantum code with sparse 1 element and has only one 4 girth in every two rows. The simulation results show that the quantum LDPC codes constructed by this method, such as GF(6t+1), GF(12t+1) have longer code length, more sparse check matrix and good performance than that of other method based on BIBDs.
