Class LatticeFromParity

Class Documentation

class UnionFindCPP::LatticeFromParity

This class implements LatticeConcept using the input of sparse parity matrix.

Public Functions

inline LatticeFromParity(uint32_t num_parities, uint32_t num_qubits, int *col_indices, int *indptr)

construct a Lattice class from a given parity matrix (CSR format)

Parameters

  • num_parities – total number of parities. Same as the number of rows of the matrix.

  • num_qubits – total number of qubits. Same as the number of columns of the matrix

  • col_indices – indices[idx] indicate the column index of the element data[idx]

  • indptr – indptr[row+1]-indptr[row] indicate the number of elements in the row
