    "abstract": "We present a straightforward scheme for creating macroscopic superpositions\nof different superfluid flow states of Bose-Einstein condensates trapped in\noptical lattices. This scheme has the great advantage that all the techniques\nrequired are achievable with current experiments. Furthermore, the relative\ndifficulty of creating cats scales favorably with the size of the cat. This\nmeans that this scheme may be well-suited to creating superpositions involving\nlarge numbers of particles. Such states may have interesting technological\napplications such as making quantum-limited measurements of angular momentum.",
