Abstract.Continuous observation of a time independent projection operator is known to prevent change of state (the quantum Zeno paradox). We discuss the recent result that generic continuous measurement of time dependent projection operators will in fact ensure change of state: an anti-Zeno paradox.
Keywords: Continuous measurements; quantum measurement theory; quantum anti-zeno paradox.
