MatrixOp

class MatrixOp(*args, **kwargs)

Bases: PrimitiveOp

Deprecated: Class for Operators represented by matrices, backed by Terra’s Operator module.

Veraltet ab Version 0.24.0: The class qiskit.opflow.primitive_ops.matrix_op.MatrixOp 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.

Parameter

• primitive – The matrix-like object which defines the behavior of the underlying function.

• coeff – A coefficient multiplying the primitive

Verursacht

• TypeError – invalid parameters.

• ValueError – 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
permute	Creates a new MatrixOp that acts on the permuted qubits.
primitive_strings	Return a set of strings describing the primitives contained in the Operator.
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_matrix_op	Returns a MatrixOp equivalent to this Operator.
