Our group works on both theory and experiment related to quantum limited measurements. This means measurements where the quantum mechanical properties of the measurement system itself become very important. For example, in many modern precision devices, the dominant source of noise comes from Heisenberg uncertainty.
For a review of this field, particularly its application to fundamental physics, see

We have two major joint experiment/theory efforts here at Berkeley, which you can read about in more detail: QuIPS and tests of quantum gravity.
