The next radically different means of information processing will be quantum computing, which researchers say will use the principles of quantum mechanics to perform complex calculations in a fraction of the time needed by the world’s fastest supercomputers.
A paper published recently in Physical Review Letters (Nov. 4 issue) has proposed an experimentally realizable circuit and an efficient scheme to implement scalable quantum computing. The ability to scale up the technology from the one or two-qubit experiments that are common in the laboratory to systems involving many qubits is what will finally make it possible to actually build a quantum computer.
"Scalable quantum computing with Josephson charge qubits," was written by Franco Nori of the University of Michigan Physics Department and the Institute of Physical and Chemical Research (RIKEN) and two colleagues, J.Q. You from RIKEN and J.S. Tsai from RIKEN and the NEC Fundamental Research Laboratories.

A study carried out by an international team of researchers and published in the journal Physical Review X shows that ion-trap technologies available today are suitable for building large-scale quantum computers. The scientists introduce trapped-ion quantum error correction protocols that detect and correct processing errors.
