    "abstract": "A major question for condensed matter physics is whether a solid-state\nquantum computer can ever be built. Here we discuss two different schemes for\nquantum information processing using semiconductor nanostructures. First, we\nshow how optically driven coupled quantum dots can be used to prepare maximally\nentangled Bell and Greenberger-Horne-Zeilinger states by varying the strength\nand duration of selective light pulses. The setup allows us to perform an\nall-optical generation of the quantum teleportation of an excitonic state in an\narray of coupled quantum dots.\n  Second, we give a proposal for reliable implementation of quantum logic gates\nand long decoherence times in a quantum dots system based on nuclear magnetic\nresonance (NMR), where the nuclear resonance is controlled by the ground state\ntransitions of few-electron QDs in an external magnetic field. The dynamical\nevolution of these systems in the presence of environmentally-induced\ndecoherence effects is also discussed.",
