# Heavy Hex Demo

The code in this repository was written as a demonstration of using stim to analyze an error correcting code, for the IBM quantum summer school.

```bash

# regenerate circuits:

./step1_make_circuits.sh

# recollect data (using pymatching)

./step2_collect_data.sh

# regenerate plots

./step3_make_plots.sh

```

Plotting logical error rate vs distance:

| X BASIS (no threshold)                | Correlated Matching                                                          | Uncorrelated Matching                                                          |
