    "abstract": "Adopting an approach similar to that of Zukowski [Phys. Rev. A 62, 032101\n(2000)], we investigate connections between teleportation and nonlocality. We\nderive a Bell-type inequality pertaining to the teleportation scenario and show\nthat it is violated in the case of teleportation using a perfect singlet. We\nalso investigate teleportation using `Werner states\u0027 of the form x P + (1-x)\nI/4, where P is the projector corresponding to a singlet state and I is the\nidentity. We find that our inequality is violated, implying nonlocality, if x \u003e\n1/sqrt(2). In addition, we extend Werner\u0027s local hidden variable model to\nsimulation of teleportation with the x = 1/2 Werner state. Thus teleportation\nusing this state does not involve nonlocality even though the fidelity achieved\nis 3/4 which is greater than the `classical limit\u0027 of 2/3. Finally, we comment\non a result of Gisin\u0027s and offer some philosophical remarks on teleportation\nand nonlocality generally.",
