    "abstract": "Equivalent-neighbor interactions of the conduction-band electron spins of\nquantum dots in the model of Imamoglu et al. [Phys. Rev. Lett. 83, 4204 (1999)]\nare analyzed. Analytical solution and its Schmidt decomposition are found and\napplied to evaluate how much the initially excited dots can be entangled to the\nremaining dots if all of them are initially disentangled. It is demonstrated\nthat the perfect maximally entangled states (MES) can only be generated in the\nsystems of up to 6 dots with a single dot initially excited. It is also shown\nthat highly entangled states, approximating the MES with a good accuracy, can\nstill be generated in systems of odd number of dots with almost half of them\nbeing excited. A sudden decrease of entanglement is observed by increasing the\ntotal number of dots in a system with a fixed number of excitations.",
