    "abstract": "We present a protocol for the teleportation of the quantum state of a pulse\nof light onto the collective spin state of an atomic ensemble. The entangled\nstate of light and atoms employed as a resource in this protocol is created by\nprobing the collective atomic spin, Larmor precessing in an external magnetic\nfield, off resonantly with a coherent pulse of light. We take here for the\nfirst time full account of the effects of Larmor precession and show that it\ngives rise to a qualitatively new type of multimode entangled state of light\nand atoms. The protocol is shown to be robust against the dominating sources of\nnoise and can be implemented with an atomic ensemble at room temperature\ninteracting with free space light. We also provide a scheme to perform the\nreadout of the Larmor precessing spin state enabling the verification of\nsuccessful teleportation as well as the creation of spin squeezing.",
