D-Wave claims massive performance boost
24 August 2015 - 10:50 | Interesting information
D-Wave Systems in British Columbia, Canada, is the only company in the world selling quantum computers, and it counts Google and NASA among its customers.
But after four years on the market there is still no clear evidence its machines can solve problems faster than ordinary computers.
Now the firm has announced the D-Wave 2X, and claims it is up to 15 times faster than regular PCs. However, outside experts contacted by New Scientist say the test is not a fair comparison.
The theory behind such computers, which exploit the weird properties of quantum mechanics, is sound. A device built using qubits, which can be both a 0 and a 1 at the same time, promises to vastly outperform regular binary bits for certain problems, like searching a database.
