library1.16.0pypypi✓ verified 84d ago

Sinter is a Python library for sampling and decoding quantum error correction circuits using Stim, with integrated support for PyMatching and various decoders. Current version 1.15.0; released roughly monthly. It provides CLI tools and a Python API for collecting statistics, plotting error curves, and managing batch jobs.

Create a repetition code circuit, sample it with PyMatching decoder, and plot error rate vs physical error probability.

import sinter import stim tasks = [ sinter.Task( circuit=stim.Circuit.generated( 'repetition_code:memory', rounds=100, distance=5 ), decoder='pymatching', ) ] sample = sinter.collect( num_workers=4, max_errors=1_000, start_batch_size=100, tasks=tasks, ) print(sample) # Plot results fig, ax = sinter.plot.error_rate_vs_error_probability(sample) fig.savefig('plot.png')

Debug

Known issues

breakingIn sinter v1.10+, the `sinter.plot.error_rate_vs_error_probability` function changed its signature: the `collection` argument is now positional-only and `show` parameter is removed.

fix

Use `sinter.plot.error_rate_vs_error_probability(sample, ax=ax)` instead of passing collection as keyword or using `show=True`.

affects: >=1.10.0

deprecated`sinter.collect()` parameter `num_workers` is deprecated in favor of `num_processes`.

fix

Replace `num_workers=4` with `num_processes=4`.

affects: >=1.13.0

gotchaIf you don't install pymatching, sinter will raise a runtime error when trying to use 'pymatching' decoder. It is not installed by default.

fix

Install pymatching via `pip install pymatching` or use a different decoder like 'fusion_blossom' that doesn't require pymatching.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'sinter'

Sinter is not installed or installed in a different environment.

fix

Run `pip install sinter` in your active Python environment.

AttributeError: module 'sinter' has no attribute 'collect'

Outdated version of sinter (<0.1). The API changed significantly in earlier versions.

fix

Upgrade to latest version: `pip install --upgrade sinter`.

RuntimeError: Failed to decode: decoder 'pymatching' not available

pymatching library is not installed.

fix

Install pymatching: `pip install pymatching`.
