    "abstract": "We investigate the generation of multipartite entangled state in a system of\nN quantum dots embedded in a microcavity and examine the emergence of genuine\nmultipartite entanglement by three different characterizations of entanglement.\nAt certain times of dynamical evolution one can generate multipartite entangled\ncoherent exciton states or multiqubit $W$ states by initially preparing the\ncavity field in a superposition of coherent states or the Fock state with one\nphoton, respectively. Finally we study environmental effects on multipartite\nentanglement generation and find that the decay rate for the entanglement is\nproportional to the number of excitons.",
