class fireopal.types.PauliOperator(paulis, coefficients=None)

Class representing a sparse Pauli operator.

paulis (str or list [ str ]) – The string representation of a Pauli operator or a list of Pauli operator strings.
coefficients (complex or list [ complex ] or np.ndarray or None , optional) – Coefficients for the Pauli operators. If not provided, the coefficients default to 1.0 for each operator.

Methods


from_dict	Construct from a dictionary containing Pauli strings and coefficients.
from_list	Construct from a list of tuples containing Pauli strings and coefficients.
from_sparse_list	Construct from a list of local Pauli strings and coefficients.
to_dict	Convert the Pauli operator to a dictionary representation.
to_list	Convert the Pauli operator to a list of tuples.
