PauliOp

class PauliOp(primitive, coeff=1.0)[Quellcode]

Bases: PrimitiveOp

Class for Operators backed by Terra’s Pauli module.

Parameter
  • primitive (Pauli) – The Pauli which defines the behavior of the underlying function.

  • coeff (Union[complex, ParameterExpression]) – A coefficient multiplying the primitive.

Verursacht

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

equals

Evaluate Equality between Operators, overloaded by ==.

eval
