quantum computing

Quantum computers could be practical in just three years from now according to a manufacturer. The technology could transform the speed and capability of computers. Oxford Ionics says it has not only produced a quantum computer chip with twice the ... performance of any existing chip, but that it could mass-produce its new design without needing specialist facilities. The idea of quantum computing has been explored for many years and aims to overcome one of the biggest limitations of traditional computing. Ultimately existing computers simply store data as either a 0 or a 1 (a bit), usually ... (view more)

Quantum computers could produce genuinely random numbers according to new research. It could boost security, an ironic effect given fears over the ways cyber criminals could use quantum computing. In extremely simplified terms, a quantum computer ... uses quantum physics in which something can exist in more than one state at a time. That's in contrast to traditional computing where data is stored in bits that represent either a 0 or a 1 at any given time. To date, the main claimed advantage of quantum computing has been processing speed. The same "bit" representing multiple states removes a ... (view more)

A theory involving donuts has helped crack a proposed government security algorithm. It's nothing to do with distracting security guards, Better Call Saul-style, but rather advanced mathematics. Government agencies and others involved in security ... are constantly looking for new ways to encrypt data, with quantum computing seen as a potentially major threat. Most encryption methods used at the moment rely on length and complexity to deter brute force cracking techniques that simply try every possible decryption key. The idea is that it should take so many tries (on average) to get the right ... (view more)
