qib.operator.pauli_operator.WeightedPauliString

class qib.operator.pauli_operator.WeightedPauliString(paulis: PauliString, weight)

Bases: AbstractOperator

Pauli string with a weight factor.

Methods

as_matrix	Generate the sparse matrix representation of the weighted Pauli string.
commutes_with	Test whether the weighted Pauli string commutes with another weighted Pauli string.
fields	List of fields the weighted Pauli string acts on.
is_hermitian	Whether the operator is Hermitian.
is_unitary	Whether the operator is unitary.
set_field	Set a field which the weighted Pauli string acts on (such that it can be used like a Hamiltonian).

Attributes
