    "abstract": "The feedback stabilization problem for ensembles of coupled spin 1/2 systems\nis discussed from a control theoretic perspective. The noninvasive nature of\nthe bulk measurement allows for a fully unitary and deterministic closed loop.\nThe Lyapunov-based feedback design presented does not require spins that are\nselectively addressable. With this method, it is possible to obtain control\ninputs also for difficult tasks, like suppressing undesired couplings in\nidentical spin systems.",
