New York Times : A quantum computer, if anyone built one, could carry out certain calculations far faster than any existing supercomputer. Physicists have already created a quantum computer’s basic building block, the qubit, from ions, atoms, quantum dots, and other tiny objects. They’ve also yoked qubits together to make logic gates. The biggest remaining challenge is to “scale up” from logic gates to a working computer. The New York Times‘s John Markoff reports that IBM Corp has decided to invest in a qubit technology, Josephson junctions, that appears to offer a clear path toward scaling up. Unlike trapped ions and some other qubit technologies, Josephson junctions can be made on chips like integrated circuits.
