    "abstract": "Many quantum key distribution analyses examine the link security in a subset\nof the full Hilbert space that is available to describe the system. In reality,\ninformation about the photon state can be embedded in correlations between the\npolarization space and other dimensions of the Hilbert space in such a way that\nEve can determine the polarization of a photon without affecting it. This paper\nuses the concept of suitability to quantify the available information for Eve,\nand then describe a systematic way to calculate and measure these\npossibilities.",
