spheres.stabilization.pytket.symmetrize_pytket_circuit(circuit_info, n_copies=2, every=1, pairwise=False, reuse_cntrls=False, measure=True)

Given a circuit specification, constructs a symmetrized version of the circuit for error correction.

Parameters

• circuit_info (dict) – Dictionary of circuit information.

• n_copies (int) – Number of copies of the original circuit to evaluate in parallel.

• every (int) – How often to perform symmetrization, i.e. every every layers.

• pairwise (bool) – Whether to symmetrize across all circuit copies or across circuit pairs.

• reuse_cntrls (bool) – Whether to to reuse control qubits from symmetrization to symmetrization. Only useful on quantum computers that allow for intermediate measurements.

• measure (bool) – Whether to measure all the non-control qubits in the end.
