10. It is interesting to note that the divergence occurs also for a classical particle-counting procedure 1. For a quantum damping process a (Formula presented) loss marks the critical value where the Wigner functions of initial states become entirely positive, see J. Janszky and T. Kobayashi, Phys. Rev. A 41, 4074 (1990) for a study of Fock states and PLRAANRef. 11 for the general case.
