On Constructing and Decoding Quantum Triorthogonal Codes
Alessio Baldelli, Olai à . Mostad, Hsuan-Yin Lin +2
A triorthogonal code is a binary quantum Calderbank-Shor-Steane (CSS) code defined by a triorthogonal matrix. Triorthogonal codes are a key ingredient in magic-state distillation,…

Improved Decoding of Quantum Tanner Codes Using Generalized Check Nodes
Olai à . 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…

Advancing Finite-Length Quantum Error Correction Using Generalized Bicycle Codes
Olai à . Mostad, Hsuan-Yin Lin, Eirik Rosnes +2
Generalized bicycle (GB) codes have emerged as a promising class of quantum error-correcting codes with practical decoding capabilities. While numerous asymptotically good quantum…
