Algorithms & Implementations
Performance Analysis
The core contribution lies in three new algorithms: SAVED_2_Γ, which uses the normalizer matrix over F4 and two Γ matrices; SAVED_1_Γ, operating on the extended normalizer matrix over F2 with one Γ matrix; and SAVED_ISOMETRY, which transforms the problem into computing the Hamming distance of a linear binary code. These algorithms are built upon adaptations of the Brouwer-Zimmermann algorithm, tailored for symplectic distance calculations of quantum stabilizer codes. They address the unique challenges of additive codes and information set construction, which are critical for quantum error correction.
An extensive experimental study on thousands of matrices demonstrated the superior performance of the new implementations. Across various datasets (mat_test3a-e), the algorithms consistently outperformed MAGMA, with speedups reaching up to 45 times in the most computationally intensive cases. The implementations also exhibited strong scalability on multicore and multiprocessor architectures, achieving nearly linear speedups when utilizing multiple cores, reducing computation times from hours to seconds for complex problems like the mat30020 dataset.
