    "abstract": "The entanglement of excitonic states in a system of $N$ spatially separated\nsemiconductor microcrystallites is investigated. The interaction among the\ndifferent microcrystallites is mediated by a single-mode cavity field. It is\nfound that the symmetric sharing of the entanglement (measured by the\nconcurrence) between any pair of the excitonic state with $N$ qubits defined by\nthe number states (vacuum and a single-exciton states) or the coherent states\n(odd and even coherent states) can be prepared by the cavity field for this\nsystem.",
