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 rand_num, int collapse) → int[source]¶

Performs measurement on the given Z-product basis.

Parameters

handle (intptr_t) – The library handle.
sv (intptr_t) – The pointer address (as Python int) to the statevector (on device).
sv_data_type (cuquantum.cudaDataType) – The data type of the statevector.
n_index_bits (uint32_t) – The number of index bits.
basis_bits –
A host array of Z-basis index bits. It can be
- an int as the pointer address to the array
- a Python sequence of index bits
n_basis_bits (uint32_t) – The number of basis bits.
rand_num (double) – A random number in [0, 1).
collapse (Collapse) – Indicate the collapse operation.

Returns

The parity measurement outcome.

Return type

int
