The underlying dynamics are modelled by either Schroedinger's equation (closed systems, state vector), or Lindblad's master equation (open systems, density matrix). Quandary solves the respective ordinary differential equation (ODE) numerically by applying a time-stepping integration scheme, and applies a gradient-based optimization scheme to design optimal control pulses that drive the quantum system to desired targets.
