Local Automorphism-Aware Syndrome Compilation for General Quantum LDPC Codes
Eugenio Durazo Rocha, Olai Å. Mostad, Hsuan-Yin Lin +1
Low-depth syndrome extraction for Calderbank-Shor-Steane (CSS) quantum low-density parity-check codes can be formulated as a proper ordered edge-coloring problem subject to quantum…

On Constructing and Decoding Quantum Triorthogonal Codes
Alessio Baldelli, Olai Å. Mostad, Hsuan-Yin Lin +2
Triorthogonal codes are a basic ingredient in magic-state distillation, as they enable transversal implementation of logical gates. As a non-Clifford operation, the $\…

Improved Decoding of Quantum Tanner Codes Using Generalized Check Nodes
Olai Å. Mostad, Eirik Rosnes, Hsuan-Yin Lin
We study the decoding problem for quantum Tanner codes and propose to exploit the underlying local code structure by grouping check nodes into more powerful generalized check nodes…
