    "abstract": "A solid state device to discriminate all the four Bell states is proposed.\nThe device is composed of controlled absorption crystals, rotators, and\nretarders. The controlled absorption, where the state of one photon affects the\nabsorption of the other photon, is realized by two photon absorption in a cubic\ncrystal. The controlled absorption crystal detects a particular Bell state and\nis transparent for the other Bell states. The rotators and retarders transform\na Bell state to another. This device may solve the problems in the early\nquantum teleportation experiments in photon polarization states.",
