    1. A Simple Model of Quantum Trajectories Todd A. Brun University of Southern California

    2. Outline Review projective and generalized measurements. A simple model of indirect measurement. Weak measurements--jump-like and diffusive. Quantum trajectories. An example of quantum jumps. An example of quantum diffusion. Decomposing strong measurements. Unraveling the master equation. Conclusions.

    3. Measurement and disturbance In quantum mechanics, one of the fundamental principles is that any measurement which gives information about a quantum system must in general also disturb that system in some way. The canonical example of this is Heisenbergs Uncertainty principle: A measurement of x disturbs the value of p, and vice versa. We call variables with this relationship complementary.
