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 ~.
assign_parameters	Binds scalar values to any Terra Parameters in the coefficients or primitives of the Operator, or substitutes one Parameter for another.
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.
permute	Permute the qubits of the circuit.
primitive_strings	Return a set of strings describing the primitives contained in the Operator.
reduce	Try collapsing the Operator structure, usually after some type of conversion, e.g.
tensor	Return tensor product between self and other, overloaded by ^.
to_circuit	Returns a QuantumCircuit equivalent to this Operator.
to_circuit_op	Returns a CircuitOp equivalent to this Operator.
to_instruction	Returns an Instruction equivalent to this Operator.
to_matrix	Return NumPy representation of the Operator.
