TL;DR

This paper establishes a unified relation between pulsed and continuous quantum measurements in the quantum Zeno effect, applicable across different coupling regimes, enhancing understanding of measurement dynamics in quantum systems.

Contribution

It generalizes previous results by deriving a relation that links pulsed and continuous measurements in the quantum Zeno effect across all coupling strengths.

Findings

Derived a formula relating pulse intervals to continuous measurement parameters

Applicable to strong, weak, and intermediate coupling regimes

Extends previous work by Schulman (1998)

Abstract

A relation is found between pulsed measurements of the excited state probability of a two-level atom illuminated by a driving laser, and a continuous measurement by a second laser coupling the excited state to a third state which decays rapidly and irreversibly. We find the time between pulses to achieve the same average detection time than a given continuous measurement in strong, weak, or intermediate coupling regimes, generalizing the results in L. S.
