| Summary:
We study rare transitions in Markovian open quantum systems driven with
Gaussian noise, applying transition path and interface sampling methods to
trajectories generated by stochastic Schr"odinger dynamics. Interface and path
sampling offer insights into rare event transition mechanisms while
simultaneously establishing a quantitative measure of the associated rate
constant. Here, we extend their domain to systems described by stochastic
Schr"odinger equations. As a specific example, we explore a model of quantum
Brownian motion in a quartic double well, consisting of a particle coupled to a
Caldeira-Leggett oscillator bath, where we note significant departures from the
Arrhenius law at low temperatures due to the presence of an anti-Zeno effect.
