    "abstract": "We study entanglement and spin squeezing in the ground state of three qubits\ninteracting via the transverse Ising model. We give analytical results for the\nentanglement and spin squeezing, and a quantitative relation between the\nconcurrence, quantifying the entanglement of two spins, and the spin squeezing\nparameter, measuring the degree of squeezing. Finally, by appropriately\nchoosing the exchange interaction and strengths of the transverse field, we\npropose a scheme for generating entangled W state from an unentangled initial\nstate with all spins down.",
