Parameters

handle (intptr_t) – The library handle.
batched_svs (intptr_t) – The pointer address (as Python int) to the batched statevectors (on device).
sv_data_type (cuquantum.cudaDataType) – The data type of the statevectors.
n_index_bits (uint32_t) – The number of index bits.
n_svs (uint32_t) – The number of batched statevectors.

n_matrices (uint32_t) – The number of matrices.
targets –
A host array of target bits. It can be
- an int as the pointer address to the array
- a Python sequence of target bits
n_targets (uint32_t) – The length of targets.
controls –
A host array of control bits. It can be
- an int as the pointer address to the array
- a Python sequence of control bits
control_bit_values –
A host array of control bit values. It can be
- an int as the pointer address to the array
- a Python sequence of control bit values
n_controls (uint32_t) – The length of controls.
compute_type (cuquantum.ComputeType) – The compute type of matrix multiplication.
workspace (intptr_t) – The pointer address (as Python int) to the workspace (on device).
workspace_size (size_t) – The workspace size (in bytes).
