Welcome to the Ramanathan Lab in the Department of Physics and Astronomy at Dartmouth College. We are an experimental research group working at the interface of quantum information processing and condensed matter physics. Our laboratory develops and uses magnetic resonance methods to control and characterize the quantum dynamics of solid state spin systems. Our experiments utilize a variety of techniques including DC, radiofrequency and microwave electronics and cryogenics. We have a number of undergraduate and graduate students working together on a variety of projects. You can find out more about the specific projects under the research tab.
