This is a simple Python script to track the evolution of Pauli operators under the action of unitaries in the Clifford group.
The unitaries are specified using a format similar to QASM, with a few minor differences.
The Python script has no dependencies outside of modules included in the default Python distribution.
This script has not been updated or tested in a long time. More complete functionality can be found in the Julia packages Clifford.jl and GateTwirl.jl.
