A critical re-examination of the quantum Zeno paradox

Abstract

The quantum Zeno paradox is defined as a negative-result experiment involving a macroscopic apparatus, and distinguished from other quantum Zeno processes. It is demonstrated that collapse of state-vector is not a requirement for the paradox, which is independent of interpretation of quantum theory. Gedanken experiments are outlined which illustrate the key features of the paradox, and its implications for the realist interpretation are discussed.
