    "abstract": "We propose a method to produce entangled states of several particles starting\nfrom a Bose-Einstein condensate. In the proposal, a single fast $\\pi/2$ pulse\nis applied to the atoms and due to the collisional interaction, the subsequent\nfree time evolution creates an entangled state involving all atoms in the\ncondensate. The created entangled state is a spin-squeezed state which could be\nused to improve the sensitivity of atomic clocks.",
