Single qubit measurements for batched state vectors.

Parameters:

handle (intptr_t) – the handle to the cuStateVec library.
batched_sv (intptr_t) – batched state vectors.
sv_data_type (int) – data type of the state vector.
n_index_bits (uint32_t) – the number of index bits.
n_svs (uint32_t) – the number of state vectors in the batched state vector.
sv_stride (int64_t) – the distance between state vectors in the batch.
bit_strings (intptr_t) – pointer to a host or device array of measured bit strings.
bit_ordering (object) –
pointer to a host array of bit string ordering. It can be:
- an int as the pointer address to the array, or
- a Python sequence of int32_t.
bit_string_len (uint32_t) – length of bitString.
randnums (object) –
pointer to a host or device array of random numbers. It can be:
- an int as the pointer address to the array, or
- a Python sequence of float.
collapse (CollapseOp) – Collapse operation.
