quantum computer

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)

Intel and IBM are battling to show off some of the most advanced 'quantum computers' ever made. It's a big step towards incredibly powerful computers that could even replicate the workings of a human brain. A quantum computer takes advantage of one ... of the most curious aspects of physics: that tiny particles can exist in two different states at the same time. This essentially allows a complete rewrite of the mathematics behind computing. Ordinary computers work by turning data into binary code: a string of 0s and 1s. In traditional computers, that involves a series of electronic 'gates' that ... (view more)
