Quantum Tech to Break Encryption Sooner than Expected

Breaking encryption using quantum computing could be 20 times easier than previously thought. It's not happening any time soon, but the point where computer security needs an overhaul may be earlier than expected. Most computer encryption today is ... based on creating an encryption key by multiplying two large prime numbers together. The beauty and simplicity is that doing this is very simple, but reversing the process to work out what the two numbers originally were is incredibly complex. While a computer can eventually figure it out, the idea is that it would take so long (potentially years or ... (view more)

Google Makes Quantum Speed, Accuracy 'Breakthrough'

Google says it's created a processor that can complete a task in five minutes that would take existing supercomputers an effectively infinite time. But it will likely be five years before the processor is ready for commercial use and experts say ... Google's boasts are somewhat selective. The Willow chip is Google's attempt at quantum computing, which is likely to be the next major advance in computing technology. In very simple terms, most traditional computers work by storing and processing data as 0s or 1s, represented by something physical (usually an electronic "gate" in a circuit) that can ... (view more)

Quantum Computing Could Be Reality Soon

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 Computing to Boost Security using Random Numbers

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)

Donut Theory Cracks Security Algorithm

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)
