Graphical Analysis of Lifted Product Code Constructions
Ragnar Freij-Hollanti, Kirsten D. Morris, Patricija Å apokaitÄ
Lifted product codes are an important family of quantum low-density parity-check (QLDPC) codes, as they were the first QLDPC code family shown to be asymptotically good. Understand…

Combinatorial Analysis of Dyadic and Quasi-Dyadic Codes
Anthony Gómez-Fonseca, Gretchen L. Matthews, Kirsten D. Morris +1
Quantum low-density parity-check (QLDPC) codes offer a promising route to scalable fault-tolerant quantum computation, but their performance under iterative decoding is strongly in…

Absorbing Sets in Quantum LDPC Codes
Kirsten D. Morris, Tefjol Pllaha, Christine A. Kelley
Iterative decoder failures of quantum low density parity check (QLDPC) codes are attributed to substructures in the code's graph, known as trapping sets, as well as degenerate erro…
