    "abstract": "We show how the partial entanglement inherent in a two mode squeezed vacuum\nstate admits two different teleportation protocols. These two protocols refer\nto the different kinds of joint measurements that may be made by the sender.\nOne protocol is the recently implemented quadrature phase approach of\nBraunstein and Kimble[Phys. Rev. Lett.{\\bf 80}, 869 (1998)]. The other is based\non recognising that a two mode squeezed vacuum state is also entangled with\nrespect to photon number difference and phase sum. We show that this protocol\ncan also realise teleportation, however limitations can arise due to the fact\nthat the photon number spectrum is bounded from below by zero. Our examples\nshow that a given entanglement resource may admit more than a single\nteleportation protocol and the question then arises as to what is the optimum\nprotocol in the general case.",
