cuquantum.custatevec.swap_index_bits¶

cuquantum.custatevec.swap_index_bits(intptr_t handle, intptr_t sv, int sv_data_type, uint32_t n_index_bits, swapped_bits, uint32_t n_swapped_bits, mask_bit_string, mask_ordering, uint32_t mask_len)[source]¶

Swap index bits and reorder statevector elements on the device.

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.
swapped_bits –
A host array of pairs of swapped index bits. It can be
- an int as the pointer address to the nested sequence
- a nested Python sequence of swapped index bits
n_swapped_bits (uint32_t) – The number of pairs of swapped index bits.
mask_bit_string –
A host array for specifying mask values. It can be
- an int as the pointer address to the array
- a Python sequence of mask values
mask_ordering –
A host array of mask ordering. It can be
- an int as the pointer address to the array
- a Python sequence of index bit ordering
mask_len (uint32_t) – The length of mask_ordering.
