Abstract

The conventional probabilistic point of view implies that if a particle has a probability p to make a transition from one site to another site, then the average transport should be <Q>=p with a variance Var(Q)=(1-p)p. In the quantum mechanical context this observation becomes a non-trivial manifestation of restricted quantum-classical correspondence. We demonstrate this observation by considering the full counting statistics which is associated with a two level coherent transition in the context of a continuous quantum measurement process. In particular we test the possibility of getting a valid result for Var(Q) within the framework of the adiabatic picture, analyzing the simplest non-trivial example of a Landau-Zener crossing.
