    "abstract": "A scheme of three-particle entanglement purification is presented in this\nwork. The physical system undertaken for investigation is dot-like single\nquantum well excitons independently coupled through a single microcavity mode.\nThe theoretical framework for the proposed scheme is based on the quantum jump\napproach for analyzing the progress of the trible-exciton entanglement as a\nseries of conditional measurement has been taken on the cavity field state. We\nfirst investigate how cavity photon affects the purity of the double-exciton\nstate and the purification efficiency in two-particle protocol. Then we extend\nthe two-particle case and conclude that the three-exciton state can be purified\ninto W state, which involves the one-photon-trapping phenomenon, with a high\nyield. Finally, an achievable setup for purification using only modest and\npresently feasible technologies is also proposed.",
