Abstract
Traditional Ramsey spectroscopy has the frequency resolution 2T, where T is the time separation between two light fields. Using squeezed states and two-atom excitation joint detection, we present a new scheme achieving a higher resolution, T. We use two-mode squeezed light, which exhibits strong entanglement.
