Class Documentation¶
-
template<class TensorNetT>
class HamiltonianTNCuda : public Pennylane::LightningTensor::TNCuda::Observables::ObservableTNCuda<TensorNetT>¶ Hamiltonian representation as a sum of observables.
- Template Parameters
TensorNetT – tensor network class.
Public Types
-
using BaseType = ObservableTNCuda<TensorNetT>¶
-
using PrecisionT = typename TensorNetT::PrecisionT¶
Public Functions
-
template<typename T1, typename T2>
inline HamiltonianTNCuda(T1 &&coeffs, T2 &&obs)¶ Create a Hamiltonian from coefficients and observables.
- Parameters
coeffs – Arguments to construct coefficients
obs – Arguments to construct observables
-
inline virtual auto getWires() const -> std::vector<std::size_t> override¶
Get the wires the observable applies to.
-
inline virtual auto getObsName() const -> std::string override¶
Get the name of the observable.
-
inline auto getObs() const -> std::vector<std::shared_ptr<ObservableTNCuda<TensorNetT>>>¶
Get the observable.
-
inline auto getCoeffs() const -> std::vector<PrecisionT>¶
Get the coefficients of the observable.
Public Static Functions
Convenient wrapper for the constructor as the constructor does not convert the std::shared_ptr with a derived class correctly.
This function is useful as std::make_shared does not handle brace-enclosed initializer list correctly.
- Parameters
coeffs – Arguments to construct coefficients
obs – Arguments to construct observables
- Returns
std::shared_ptr<HamiltonianTNCuda<TensorNetT>>
