Template Function Pennylane::LightningQubit::Gates::callSparseMatrixOp

Function Documentation

template<class PrecisionT, class IndexT = std::size_t>
inline void Pennylane::LightningQubit::Gates::callSparseMatrixOp(SparseMatrixFuncPtrT<PrecisionT, IndexT> func, std::complex<PrecisionT> *data, std::size_t num_qubits, const IndexT *row_map_ptr, const IndexT *col_idx_ptr, const std::complex<PrecisionT> *values_ptr, const std::vector<std::size_t> &wires, bool adj = false)

Call a sparse matrix operation.

Template Parameters

  • PrecisionT – Floating point type for the state-vector.

  • IndexT – Index type for the sparse matrix.

Parameters

  • func – Function pointer for the gate operation.

  • data – Data pointer the gate is applied to

  • num_qubits – The number of qubits of the state-vector.

  • row_map_ptr – Pointer to the row map of the sparse matrix.

  • col_idx_ptr – Pointer to the column index of the sparse matrix.

  • values_ptr – Pointer to the values of the sparse matrix.

  • wires – Wires the gate applies to.

  • adj – If true, we apply the adjoint of the gate.
