Per-Device Weight Tuning Reduces Logical Error Rate by 31% vs Uniform-Weight MWPM on Superconducting Devices
E. Sorensen, M. Voss · arXiv:2511.XXXXX
We demonstrate that incorporating device-specific gate error rates and T1/T2 times into the MWPM edge weight matrix yields substantial improvements in logical error suppression compared to a uniform-weight baseline. Results are reported for synthetic noise models calibrated from three commercial superconducting processors at code distances d=5 and d=7.
Union-Find Decoder Benchmark Suite: Methodology and Reproducibility Guide
QECSync Engineering Team · Technical Report TR-2025-01
A description of our benchmarking methodology for Union-Find decoder latency and accuracy measurements. Includes noise model definitions, hardware parameter ranges, and the open-source simulation harness used to generate all reported numbers. Intended to enable independent replication.
Magic State Distillation Resource Overhead Under Realistic Noise Constraints
E. Sorensen, J. Okafor · arXiv:2409.XXXXX
Analysis of factory count and qubit overhead for T-gate distillation as a function of physical error rate and code distance. We show that compiler-aware factory scheduling reduces total qubit overhead by 18–24% compared to static factory count estimates, across a range of circuit T-counts from 10 to 10,000 T-gates.
Hardware-Agnostic QEC Software: Design Principles and Early Results
E. Sorensen · Quantum Error Correction Workshop 2023, Boulder, CO
Presentation of early QECSync architecture decisions, the DeviceSpec abstraction layer design, and initial benchmark data comparing hardware-tuned vs hardware-agnostic decoder configurations.
QECSync's decoder implementation is grounded in the body of work on topological quantum codes and efficient decoding algorithms, particularly the surface code and its variants.
