Public Functions
-
inline NamedObsBase(std::string obs_name, std::vector<std::size_t> wires, std::vector<PrecisionT> params = {})¶
Construct a NamedObsBase object, representing a given observable.
- Parameters
obs_name – Name of the observable.
wires – Argument to construct wires.
params – Argument to construct parameters
-
inline virtual auto getObsName() const -> std::string override¶
Get the name of the observable.
-
inline virtual auto getWires() const -> std::vector<std::size_t> override¶
Get the wires the observable applies to.
-
inline virtual void applyInPlace(StateVectorT &sv) const override¶
Apply the observable to the given statevector in place.
-
inline virtual void applyInPlaceShots(StateVectorT &sv, std::vector<std::vector<PrecisionT>> &eigenValues, std::vector<std::size_t> &ob_wires) const override¶
Apply unitaries of an observable to the given statevector in place.
- Parameters
sv – Reference to StateVector object.
eigenValues – Eigenvalues of an observable.
ob_wires – Reference to a std::vector object which stores wires of the observable.
