Functions for running ops on states.
QubitOp | Types of unitary ops which can be applied to a state.
|
apply_op | Apply op to the input , storing the results in output . If either start at a nonzero state
index in their 0th index, use input/output_offset .
|
apply_ops | Apply ops to the input , storing the results in output . If either start at a nonzero state
index in their 0th index, use input/output_offset .
This is much less efficient as compared to repeated applications of apply_op , if your ops can
be applied in sequence, do so with apply_op .
|
from_reals | Make a vector of complex numbers whose reals are given by data
|
from_tuples | Make a vector of complex numbers whose reals are given by the first tuple entry in data and
whose imaginaries are from the second.
|
full_to_sub | Get the index for a submatrix indexed by indices given the full_index for the larger 2^n by 2^n matrix.
|
get_index | Get the i th qubit index for op
|
make_control_op | Make a Control QubitOp
|
make_function_op | Make a Function QubitOp
|
make_matrix_op | Make a Matrix QubitOp
|
make_op_matrix | Make the full op matrix from ops .
Not very efficient, use only for debugging.
|
make_sparse_matrix_from_function | Make a vector of vectors of rows (with (column, value) ) built from a function
f which takes row numbers.
natural_order indicates that the lowest indexed qubit is the least significant bit in row and
the output column from f
|
make_sparse_matrix_op | Make a SparseMatrix QubitOp from a vector of rows (with (column, value) ).
natural_order indicates that the lowest indexed qubit is the least significant bit in column
and row where row is the index of dat .
|
make_swap_op | Make a Swap QubitOp
|
num_indices | Get the number of indices represented by op
|
select_matrix_coords | Given the full matrix row and col , find the given op's row and column using the full n ,
the op's nindices , the op's `indices'.
|
sub_to_full | Given the sub_index for the submatrix, and a base to overwrite values, get the full index for the 2^n by 2^n matrix.
