graphix-stim-compiler

Clifford compilation pass using stim functionalities.

This compilation pass together with the new tools implemented in matulni/graphix.git@circuit-extraction allow to do a round-trip conversion circuit -> MBQC pattern -> circuit.

Example

from graphix_stim_compiler import cm_stim_pass

from graphix.transpiler import Circuit
from graphix.fundamentals import ANGLE_PI

import numpy as np

qc = Circuit(2)
qc.cnot(1, 0)
qc.rz(0, 0.2 * ANGLE_PI)
qc.h(0)
qc.rx(1, 0.2 * ANGLE_PI)

pattern = qc.transpile().pattern

qc_extracted = pattern.extract_opengraph().infer_pauli_measurements().extract_pauli_flow().extract_circuit().to_circuit(cm_cp=cm_stim_pass)

s_ref = qc.simulate_statevector().statevec
s_extracted = qc_extracted.simulate_statevector().statevec
assert s_ref.isclose(s_extracted)

Installation

git clone the repository and run

cd graphix-stim-compiler
pip install .
