The time evolution of an unstable quantum system is quadratic at short times (the so-called quantum Zeno region), and follows a power law at long times. The quantum Zeno region has been confirmed in a plethora of experiments, with very different quantum systems and experimental platforms. On the other hand, the power law regime is elusive and very difficult to observe, essentially because the initial states are strongly depleted by intermediate exponential evolution.

After analyzing the problem from a theoretical point of view, we will review some experiments and discuss concepts and applications.
