    "abstract": "The generation and detection of maximally-entangled two-particle states,\n`Bell states,\u0027 are crucial tasks in many quantum information protocols such as\ncryptography and teleportation. Unfortunately, they require strong\ninter-particle interactions lacking in optics. For this reason, it has not\npreviously been possible to perform complete Bell state determination in\noptical systems. In this work, we show how a recently developed quantum\ninterference technique for enhancing optical nonlinearities can make efficient\nBell-state measurement possible. We also discuss weaknesses of the scheme\nincluding why it cannot be used for unconditional quantum teleportation.",
