Class Documentation¶
-
template<typename T>
class Observable¶ A base class for all observable classes.
We note that all subclasses must be immutable (does not provide any setter).
- Template Parameters
T – Floating point type
Subclassed by Pennylane::Algorithms::Hamiltonian< T >, Pennylane::Algorithms::HermitianObs< T >, Pennylane::Algorithms::NamedObs< T >, Pennylane::Algorithms::TensorProdObs< T >
