qecsim is a Python 3 package for simulating quantum error correction using stabilizer codes.

It provides access to all features via a command-line interface. It can also be used as a library via the fully-documented API. It includes many common codes, error models and decoders, and can be extended with additional components.

Install and upgrade using pip:

$ pip install -U qecsim

$ qecsim --version
qecsim, version 1.0b9
$ qecsim --help                 # console script
...
$ python -O -m qecsim --help    # module script with Python options e.g. -O for optimize
...

>>> import qecsim
>>> qecsim.__version__
'1.0b9'
>>> from qecsim import app
>>> help(app)
...

qecsim can be extended with additional codes, error models and decoders that integrate into the command-line interface. See https://github.com/qecsim/qecsimext for a basic example.
