    "abstract": "We present a set of concrete and realistic ideas for the implementation of a\nsmall-scale quantum computer using electron spins in lateral GaAs/AlGaAs\nquantum dots. Initialization is based on leads in the quantum Hall regime with\ntunable spin-polarization. Read-out hinges on spin-to-charge conversion via\nspin-selective tunneling to or from the leads, followed by measurement of the\nnumber of electron charges on the dot via a charge detector. Single-qubit\nmanipulation relies on a microfabricated wire located close to the quantum dot,\nand two-qubit interactions are controlled via the tunnel barrier connecting the\nrespective quantum dots. Based on these ideas, we have begun a series of\nexperiments in order to demonstrate unitary control and to measure the\ncoherence time of individual electron spins in quantum dots.",
