Abstract
We report the generation of a macroscopic singlet state in a cold atomic sample via quantum non- demolition (QND) measurement induced spin squeezing. We observe 3 dB of spin squeezing and detect entanglement with 5σ statistical significance using a generalized spin squeezing inequality. The degree of squeezing implies at least 50% of the atoms have formed singlets.
