With rigorous formulations of noise and disturbance, a model of a measuring interaction demonstrates that this formulation of the Heisenberg uncertainty principle is by no means universally valid. An experimental realization of the model is also suggested.         Home | About the Program | Our Research | Publications | People Related MURIs | Contact © Massachusetts Institute of Technology
