Temporal Bell inequalities can be violated for sequences of events (hi
stories) for which probabilities satisfying consistent sum rules canno
t be defined. We discuss possible experiments in which such violations
, never observed so far, may indeed be seen. The basic scheme, which u
ses three optically driven and mutually interacting two-level systems,
could be implemented in a variety of nanostructures. It could even be
mapped onto the dynamics of a single electron four-level system thus
allowing for a realization in atomic physics.
