Computes the time propagation of a quantum state under the action of the operator.

Parameters:

handle (intptr_t) – Library handle.
time_propagation (intptr_t) – Time propagation object.
time_step_real (double) – Real part of time step for propagation.
time_step_imag (double) – Imaginary part of time step for propagation.
time (double) – Time value.
batch_size (int64_t) – Batch size (>=1).
num_params (int32_t) – Number of variable parameters defined by the user.
params (intptr_t) – GPU-accessible pointer to an F-order 2d-array of user-defined real parameter values: params[num_params, batch_size].
state_in (intptr_t) – Input quantum state (can be batched).
state_out (intptr_t) – Time propagated output quantum state (can be batched).
workspace (intptr_t) – Allocated workspace descriptor.
stream (intptr_t) – CUDA stream.
