    "abstract": "We propose a scheme for generation of arbitrary coherent superposition of\nvortex states in Bose-Einstein condensates (BEC) using the orbital angular\nmomentum (OAM) states of light. We devise a scheme to generate coherent\nsuperpositions of two counter-rotating OAM states of light using known\nexperimental techniques. We show that a specially designed Raman scheme allows\ntransfer of the optical vortex superposition state onto an initially\nnon-rotating BEC. This creates an arbitrary and coherent superposition of a\nvortex and anti-vortex pair in the BEC. The ideas presented here could be\nextended to generate entangled vortex states, design memories for the OAM\nstates of light, and perform other quantum information tasks. Applications to\ninertial sensing are also discussed.",
