This is an example of the Zeno effect that has remarkable pedagogical interest because of its conceptual simplicity, easy implementation, low cost, and because the same the Zeno effect holds at classical and quantum levels. An added value is the demonstration of the Zeno effect beyond typical idealized assumptions in a practical setting with real polarizers.engjournal articlehttp://dx.doi.org/10.1088/0143-0807/36/4/045001http://iopscience.iop.org/open access535Quantum-theoryApparatusParadoxÓptica (Física)2209.19 Óptica Física
