HGNN BB QLDPC Syndrome Datasets

Stim-generated syndrome–logical flip datasets for Hypergraph Neural Network (HGNN) decoders on Bivariate Bicycle (BB) quantum LDPC memory circuits.

Dataset batches

Subfolder	Shots / p	Approx. size	Zenodo DOI
`bb_10000/`	10⁴	~200 MB	`{{ZENODO_DOI_bb_10000}}`
`bb_100000/`	10⁵	~750 MB	`{{ZENODO_DOI_bb_100000}}`

`bb_10000000/`	10⁷	~59 GB	`{{ZENODO_DOI_bb_10000000}}`

Each batch contains 8 datasets: pub_bb_d{3,5,7,12}_{depol,cln}.

Download and extract

Files are stored as bb_<batch>_pub_bb_<name>.tar.gz archives.

pip install huggingface_hub
huggingface-cli download ramazankatirci/hgnn-bb-qldpc --repo-type dataset --local-dir ./hgnn-bb-qldpc

mkdir -p datasets/bb_100000
tar -xzf hgnn-bb-qldpc/bb_100000/bb_100000_pub_bb_d5_depol.tar.gz -C datasets/bb_100000

Verify integrity with SHA256SUMS in each batch folder.

Data fields

Per p_* run directory:

File / array	Shape	Description
`hypergraph.npz`	static	DEM-derived hypergraph (detectors = nodes)
`shard_*.zarr/syndrome`	`(N, num_detectors)` uint8	Detector flips (HGNN input)
`shard_*.zarr/logical`	`(N, k)` uint8	Logical observable flips (labels)
`shard_*.zarr/T1_us,T2_us,Fgate`	`(N,)` float32	Synthetic FiLM calibration metadata

See manifest.json in each dataset folder for run index and BB code parameters.

Usage with this repository

from train.dataset_pyg import ManifestQECDataset

ds = ManifestQECDataset("datasets/bb_100000/pub_bb_d5_depol/manifest.json")
print(len(ds), ds.num_nodes)

python -m train.train_hgnn \
  --manifest datasets/bb_100000/pub_bb_d5_depol/manifest.json \
  --epochs 50

Generation

Software: HGNN @ {{GIT_SHA}}
Noise: depolarizing (*_depol) or circuit-level (*_cln, T1=80µs, T2=50µs, F2q=0.995)
Hypergraph: max_hyperedges=full (no DEM truncation)
p values: 5e-4 … 2e-2 (8 points)
