    "abstract": "We discuss level schemes of small quantum-dot turnstiles and their\napplicability in the production of entanglement in two-photon emission. Due to\nthe large energy splitting of the single-electron levels, only one single\nelectron level and one single hole level can be made resonant with the levels\nin the conduction band and valence band. This results in a model with nine\ndistinct levels, which are split by the Coulomb interactions. We show that the\noptical selection rules are different for flat and tall cylindrically symmetric\ndots, and how this affects the quality of the entanglement generated in the\ndecay of the biexciton state. The effect of charge carrier tunneling and of a\nresonant cavity is included in the model.",
