cuquantum.bindings.cudensitymat.state_get_component_info( intptr_t handle, intptr_t state, int32_t state_component_local_id, intptr_t state_component_global_id, intptr_t state_component_num_modes, intptr_t state_component_mode_extents, intptr_t state_component_mode_offsets, )[source]#

Queries information for a locally stored component tensor which represents either the full component or its slice (on the current process in multi-process runs).

Parameters:

handle (intptr_t) – Library handle.
state (intptr_t) – Quantum state (or a batch of quantum states).
state_component_local_id (int32_t) – Component local id (on the current parallel process).
state_component_global_id (intptr_t) – Component global id (across all parallel processes).
state_component_num_modes (intptr_t) – Number of modes in the queried component tensor.
state_component_mode_extents (intptr_t) – Component tensor mode extents (the size of the array must be sufficient, see cudensitymatStateGetComponentNumModes).
state_component_mode_offsets (intptr_t) – Component tensor mode offsets defining the locally stored slice (the size of the array must be sufficient, see cudensitymatStateGetComponentNumModes).
