PauliSumOp

class PauliSumOp(*args, **kwargs)

ベースクラス: PrimitiveOp

Deprecated: Class for Operators backed by Terra’s SparsePauliOp class.

バージョン 0.24.0 で非推奨: The class qiskit.opflow.primitive_ops.pauli_sum_op.PauliSumOp is deprecated as of qiskit-terra 0.24.0. It will be removed no earlier than 3 months after the release date. For code migration guidelines, visit https://qisk.it/opflow_migration.

パラメータ

• primitive – The SparsePauliOp which defines the behavior of the underlying function.

• coeff – A coefficient multiplying the primitive.

• grouping_type – The type of grouping. If None, the operator is not grouped.

例外

TypeError – invalid parameters.

Methods Defined Here

add	Return Operator addition of self and other, overloaded by +.
adjoint	Return a new Operator equal to the Operator's adjoint (conjugate transpose), overloaded by ~.
compose	Return Operator Composition between self and other (linear algebra-style: A@B(x) = A(B(x))), overloaded by @.
equals	Evaluate Equality between Operators, overloaded by ==.
eval	Evaluate the Operator's underlying function, either on a binary string or another Operator.
exp_i	Return a CircuitOp equivalent to e^-iH for this operator H.
from_list	Construct from a pauli_list with the form [(pauli_str, coeffs)]
is_hermitian	Return True if the operator is hermitian.
is_zero	Return this operator is zero operator or not.
matrix_iter	Return a matrix representation iterator.
mul	Returns the scalar multiplication of the Operator, overloaded by *, including support for Terra's Parameters, which can be bound to values later (via bind_parameters).
permute	Permutes the sequence of PauliSumOp.
primitive_strings	Return a set of strings describing the primitives contained in the Operator.
reduce	Simplify the primitive SparsePauliOp.
tensor	Return tensor product between self and other, overloaded by ^.
to_instruction	Returns an Instruction equivalent to this Operator.
to_matrix	Return NumPy representation of the Operator.
to_pauli_op	Returns a sum of PauliOp s equivalent to this Operator.
to_spmatrix	Returns SciPy sparse matrix representation of the PauliSumOp.
