initial_state

property Model.initial_state: ndarray | Array

Initial state used when state_only=True simulations are requested.

The value should be a state vector in the model’s full Hilbert space. When left as None, simulate_time_evolution() requires state_only=False.

Hint

Set this when you want Simphony to propagate a specific state vector instead of full propagators. It is mutually exclusive with initial_density_matrix.
