Module qip_iterators::iterators

Structs

• ControlledOpIterator
  Iterator which provides the indices of nonzero columns for a given row of a COp
• FunctionOpIterator
  Iterator which provides the indices of nonzero columns for a given function.
• MatrixOpIterator
  Iterator which provides the indices of nonzero columns for a given row of a matrix
• MultiOpIterator
  Iterator which provides the indices of nonzero columns for a given row for a collection of ops.
• SparseMatrixOpIterator
  Iterator which provides the indices of nonzero columns for a given row of a sparse matrix
• SwapOpIterator
  Iterator which provides the indices of nonzero columns for a given row of a SwapOp

Enums

• UnitaryOp
  Ops which can be applied to quantum states.

Functions

• act_on_iterator
  Apply function f to the iterator for op, return result.
• fold_for_op_cols
  Fold across rows hitting nonzero columns.
• num_indices
  Get the number of indices represented by op
• sum_for_op_cols
  Using the function f which maps from a column and row to a complex value for the op matrix, sums for all nonzero entries for a given op more efficiently than trying each column between 0 and 2^nindices. This really needs to be cleaned up, but runs in a tight loop. This makes it hard since Box is unfeasible and the iterator types aren’t the same size.
• sum_for_ops_cols
  Like sum_for_op_cols but takes multiple ops at once.
