dotg

It's a preliminary name!

A small package for running quantum error correction simulations in stim. At the moment only quantum memory experiments are available, but I plan to add stability experiments in soon.

Originally planned to be a specific implementation of Union Find, I realised I needed a package to test any new decoder on, and existing decoders to compare it to. So I built this.

The module tree is as such:

dotg/
├─ experiments/
├─ src/
│  ├─ dotg/
│  │  ├─ circuits
│  │  ├─ decoders
│  │  ├─ noise
│  │  ├─ utilities/
|  │  │  ├─ stim_assets
├─ tests/
├─ coverage.sh
├─ pyproject.toml

The package can be built with poetry using poetry install.

TO DO

• Add some kind of circuit building functionality. A class (or group of classes) that allows for stim circuits to be built iteratively. Necessary for other items on this list.
• In circuits:
  • Add stability experiments
  • Add XY and XZZX codes to surface code family.
• In decoders:
  • Manager class to allow for safe parallelisation
  • Finish partial decoders
  • Write implementation of Union Find (will be separate repository).
• In noise:
  • More noise models!
• In utilities:
  • Compilation to other gate sets, and enforcing gate sets.
  • Circuit optimisation
