    "abstract": "We study a configuration of devices that includes (1) a source of some\nunknown bipartite quantum state that is claimed to be the Bell state $\\Phi^+$\nand (2) two commuting but otherwise unknown measurement apparatus, one on each\nside, that are each claimed to execute an orthogonal measurement at an angle\n$\\theta \\in \\{0, \\pi/8, \\pi/4\\}$ that is chosen by the user. We show that, if\nthe nine distinct probability distributions that are generated by the self\nchecking configuration, one for each pair of angles, are consistent with the\nspecifications, the source and the two measurement apparatus are guaranteed to\nbe identical modulo some isomorphism to the claimed specifications. We discuss\nthe connection with quantum cryptography.",
