    "abstract": "A study on the cause of the multi-particle entanglement is presented in this\nwork. We investigate how dot-like single quantum well excitons, which are\nindependently coupled through a single microcavity mode, evolve into maximally\nentangled state as a series of conditional measurements are taken on the cavity\nfield state. We first show how cavity photon affects the entanglement purity of\nthe double-exciton Bell state and the triple-exciton W state. Generalization to\nmulti-excitons W states is then derived analytically. Our results pave the way\nfor studying the crucial cause of multi-particle collective effect.",
