    "abstract": "We present an application of particle statistics to the problem of optimal\nambiguous discrimination of quantum states. The states to be discriminated are\nencoded in the internal degrees of freedom of identical particles, and we use\nthe bunching and antibunching of the external degrees of freedom to\ndiscriminate between various internal states. We show that we can achieve the\noptimal single-shot discrimination probability using only the effects of\nparticle statistics. We discuss interesting applications of our method to\ndetecting entanglement and purifying mixed states. Our scheme can easily be\nimplemented with the current technology.",
