Abstract
In this work we generalize the quantum trajectory (QT) theory from Markovian to non-Markovian environments. We model the non-Markovian environment by using a Lorentzian spectral density function with bandwidth , and find a perfect “scaling” property with the measurement frequency in terms of the scaling variable . Our result bridges the gap between the existing QT theory and the Zeno effect, by rendering them as two extremes corresponding to and , respectively. This -dependent criterion improves the idea of using alone and quantitatively identifies the validity condition of the conventional QT theory.
