cuquantum.bindings.custatevecEx.abs2sum_array( intptr_t state_vector, intptr_t abs2sum, output_ordering, int32_t output_ordering_len, mask_bit_string, mask_wire_ordering, int32_t mask_len, )[source]#

Calculate abs2sum array for a given set of wires.

Parameters:

state_vector (intptr_t) – StateVector instance.
abs2sum (intptr_t) – pointer to a host or device array of sums of squared absolute values.
output_ordering (object) –
pointer to a host array of output tensor ordering. It can be:
- an int as the pointer address to the array, or
- a Python sequence of int32_t.
output_ordering_len (int32_t) – the length of output_ordering.
mask_bit_string (object) –
pointer to a host array for a bit string to specify mask bits. It can be:
- an int as the pointer address to the array, or
- a Python sequence of int32_t.
mask_wire_ordering (object) –
pointer to a host array that specifies the wire ordering of mask_bit_string. It can be:
- an int as the pointer address to the array, or
- a Python sequence of int32_t.
mask_len (int32_t) – the length of mask.
