Threshold Improvement of Low-Density Lattice Codes via Spatial Coupling
Hironori Uchikawa, Brian M. Kurkoski, Kenta Kasai +1
Spatially-coupled low-density lattice codes (LDLC) are constructed using protographs. Using Monte Carlo density evolution using single-Gaussian messages, we observe that the thresh…

Spatially Coupled Quasi-Cyclic Quantum LDPC Codes
Manabu Hagiwara, Kenta Kasai, Hideki Imai +1
We face the following dilemma for designing low-density parity-check codes (LDPC) for quantum error correction. 1) The row weights of parity-check should be large: The minimum dist…
