cuquantum.custatevec.measure_on_z_basis¶

cuquantum.custatevec.measure_on_z_basis(intptr_t handle, intptr_t sv, int sv_data_type, uint32_t n_index_bits, basis_bits, uint32_t n_basis_bits, double randnum, int collapse) → int32_t[source]¶

Measurement on a given Z-product basis.

Parameters

handle (intptr_t) – the handle to the cuStateVec library.
sv (intptr_t) – state vector.
sv_data_type (int) – data type of state vector.
n_index_bits (uint32_t) – the number of index bits.
basis_bits (object) –
pointer to a host array of Z basis bits. It can be:
- an int as the pointer address to the array, or
- a Python sequence of int32_t.
n_basis_bits (uint32_t) – the number of Z basis bits.
randnum (double) – random number, [0, 1).
collapse (CollapseOp) – Collapse operation.

Returns

parity, 0 or 1.

Return type

int32_t
