Nanowires may provide innards for quantum computers


SEMICONDUCTING nanowires could one day store and process data in quantum computers. A team of researchers led by Silvano De Franceschi of the Delft University of Technology in the Netherlands made nanowires out of indium arsenide, each about 100 nanometres in diameter and 100 times as long. By attaching aluminium electrodes to the ends of the wires, they could probe the wires’ behaviour at temperatures close to absolute zero. At such temperatures aluminium becomes superconducting,
