inline JacobianDataMPI(std::size_t num_params, const StateVectorT &sv, std::vector<std::shared_ptr<Observable<StateVectorT>>> obs, OpsData<StateVectorT> ops, std::vector<std::size_t> trainP)

Construct a JacobianDataMPI object.

Each value \(i\) in trainable params means that we want to take a derivative respect to the \(i\)-th operation.

Further note that ops does not contain state preparation operations (e.g. StatePrep) or Hamiltonian coefficients.

Parameters

• num_params – Number of parameters in the Tape.

• sv – Referemce to the statevector.

• obs – Observables for which to calculate Jacobian.

• ops – Operations used to create given state.

• trainP – Sorted list of parameters participating in Jacobian computation.
