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…
Advancing Finite-Length Quantum Error Correction Using Generalized Bicycle Codes
Olai Å. 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…
Generalizing Quantum Tanner Codes
Olai Å. Mostad, Eirik Rosnes, Hsuan-Yin Lin
In this work, we present a generalization of the recently proposed quantum Tanner codes by Leverrier and Zémor, which contains a construction of asymptotically good quantum LDPC co…
