    "abstract": "Experimental methods for laser-control of trapped ions have reached\nsufficient maturity that it is possible to set out in detail a design for a\nlarge quantum computer based on such methods, without any major omissions or\nuncertainties. The main features of such a design are given, with a view to\nidentifying areas for study. The machine is based on 13000 ions moved via 20\nmicron vacuum channels around a chip containing 160000 electrodes and\nassociated classical control circuits; 1000 laser beam pairs are used to\nmanipulate the hyperfine states of the ions and drive fluorescence for readout.\nThe computer could run a quantum algorithm requiring 10^9 logical operations on\n300 logical qubits, with a physical gate rate of 1 MHz and a logical gate rate\nof 8 kHz, using methods for quantum gates that have already been experimentally\nimplemented. Routes for faster operation are discussed.",
