We prove that the quantum trajectory of repeated perfect measurement on a finite quantum system either asymptotically purifies, or hits upon a family of 'dark' subspaces, where the time evolution is unitary. * This paper is dedicated to Mike Keane on his 65-th birthday Keywords and phrases: quantum trajectory, stochastic Schrödinger equation imsart-lnms ver. 2005/02/28 file: Maassen.tex date: May 11, 2005 Hans Maassen/Quantum trajectories
