openfermion.transforms.fix_single_term

Auxiliary function for term reductions.

Automatically multiplies a single term with a given stabilizer if the Pauli operator on a given qubit is of one of two specified types. This fixes a certain representation of a logical operator.

term (QubitOperator): Single term to fix. position (int): Index of the qubit which is to be fixed. fixed_op (str): Pauli operator, which will cause a multiplication by the stabilizer when encountered at the fixed position. other_op (str): Alternative Pauli operator, which will also cause the multiplication by the stabilizer. stabilizer (QubitOperator): Stabilizer that is multiplied when necessary.

term (QubitOperator): Updated term in a fiixed representation.
