    "abstract": "We exploit the analogy between tunnelling across a potential barrier and\nAharonov\u0027s weak measurements to resolve the long standing paradox between the\nimpossibility to exceed the speed of light and the seemingly \u0027superluminal\u0027\nbehaviur of the tunnelling particle in the barrier. We demonstrate that\n\u0027superluminality\u0027 occurs when the value of the duration $\\tau$ spent in the\nbarrier is uncertain, whereas when $\\tau$ is known accurately, no\n\u0027superluminal\u0027 behaviur is observed. In all cases only subluminal durations\ncontribute to the transmission, which precludes faster-than-light information\ntransfer, as shown by a recent experiment.",
