    "abstract": "Quantum trajectory theory, developed largely in the quantum optics community\nto describe open quantum systems subjected to continuous monitoring, has\napplications in many areas of quantum physics. In this paper I present a simple\nmodel, using two-level quantum systems (q-bits), to illustrate the essential\nphysics of quantum trajectories and how different monitoring schemes correspond\nto different ``unravelings\u0027\u0027 of a mixed state master equation. I also comment\nbriefly on the relationship of the theory to the Consistent Histories formalism\nand to spontaneous collapse models.",
