Options(
    save_states: bool = True,
    verbose: bool = True,
    cartesian_batching: bool = True,
    t0: ScalarLike | None = None,
    save_extra: callable[[Array], PyTree] | None = None,
)

Generic options for the quantum solvers.

Parameters

• save_states –

  If True, the state is saved at every time in tsave, otherwise only the final state is returned.

• verbose –

  If True, print information about the integration, otherwise nothing is printed.

• cartesian_batching –

  If True, batched arguments are treated as separated batch dimensions, otherwise the batching is performed over a single shared batched dimension.

• t0 –

  Initial time. If None, defaults to the first time in tsave.

• save_extra (function, optional) –

  A function with signature f(Array) -> PyTree that takes a state as input and returns a PyTree. This can be used to save additional arbitrary data during the integration.
