摘要：

Ramsey spectroscopy with a spin-squeezed input state is considered to show squeezed spin state (SSS) as a useful resource of entanglement. SSS possesses pair-wise quantum relations which helps in improving spectroscopic precision in the presence of decoherence. It is shown that with an icreasing number of ions, the improvement in precision asymptotically saturates at the theoretical decoherence.
