calculations

Two sets of researchers into quantum computing have announced very different sets of results. One claim they've already achieved more powerful performance than a traditional computer, while the others say they've confirmed the potential for ... performing genuinely useful tasks. Quantum computing aims to take advantage of the way particles can exist in more than one state at a time. That compares with traditional computers which store data in bits, each of which is either a 0 or a 1. In principle at least, a quantum computer could be made up of "qbits" and perform calculations dramatically faster ... (view more)
