cuquantum.bindings.cudensitymat.operator_compute_action¶

cuquantum.bindings.cudensitymat.operator_compute_action(intptr_t handle, intptr_t superoperator, double time, int32_t num_params, params, intptr_t state_in, intptr_t state_out, intptr_t workspace, intptr_t stream)[source]¶

Computes the action of the operator on a given input quantum state, accumulating the result in the output quantum state (accumulative action).

Parameters

handle (intptr_t) – Library handle.
superoperator (intptr_t) – Operator.
time (double) – Time value.
num_params (int32_t) – Number of variable parameters defined by the user.
params (object) –
Variable parameters defined by the user. It can be:
- an int as the pointer address to the array, or
- a Python sequence of float.
state_in (intptr_t) – Input quantum state (or a batch of input quantum states).
state_out (intptr_t) – Updated resulting quantum state which accumulates operator action on the input quantum state.
workspace (intptr_t) – Allocated workspace descriptor.
stream (intptr_t) – CUDA stream.
