Quantum Zeno paradox

The obstruction of the ion s evolution was said comprehensible, at least in principle, in terms of physical reaction of the apparatus on the ion ensemble, and as such not being too surprising. Only the non-local correlation of system and meter, and a null result of the detection, however, would exclude dynamical coupling and qualify as back-action-free measurement. Such a procedure would prove the obstruction of the evolution by measurement, that is, by gain of information, and would establish a real QZE, or "quantum Zeno paradox" (QZP) [21].
