cuquantum.custatevec.batch_measure_with_offset(intptr_t handle, intptr_t sv, int sv_data_type, uint32_t n_index_bits, intptr_t bit_string, bit_ordering, uint32_t bit_string_len, double randnum, int collapse, double offset, double abs2sum)[source]¶

Batched single qubit measurement for partial vector.

Parameters

handle (intptr_t) – the handle to the cuStateVec library.
sv (intptr_t) – partial state vector.
sv_data_type (int) – data type of the state vector.
n_index_bits (uint32_t) – the number of index bits.
bit_string (intptr_t) – pointer to a host array of measured bit string.
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 bit_string.
randnum (double) – random number, [0, 1).
collapse (CollapseOp) – Collapse operation.
offset (double) – partial sum of squared absolute values.
abs2sum (double) – sum of squared absolute values for the entire state vector.
