What is a D-Wave quantum computer?
D-Wave’s quantum computers use very different technology to that found in everyday computers. The latest D-Wave machine is 10-feet tall, costs $15m and tackles problems using quantum transistors, tiny loops of niobium cooled to close to absolute zero (-459.6F) by liquid helium.
How do quantum computers work?
This superposition of states鈥攁long with the other quantum mechanical phenomena of entanglement and tunneling鈥攅nables quantum computers to manipulate enormous combinations of states at once. D-Wave systems use a process called quantum annealing to search for solutions to a problem.
What is the D-Wave 2000Q quantum annealer?
D-Wave, a company based in British Columbia, has announced a new version of its quantum annealer: the D-Wave 2000Q. As the name suggests, the number of bits has increased from about 1,000 to just over 2,000. This is, for D-Wave, an important step on its roadmap to world domination.
Why don鈥檛 we have a 鈥榬eal鈥?quantum computer?
鈥淭hat鈥檚 the reason some people say we don鈥檛 have a 鈥榬eal鈥?quantum computer鈥攂ecause D-Wave鈥檚 is not a 鈥榰niversal鈥?computer.鈥?D-Wave鈥檚 quantum computer, rather, only solves optimization problems, that is ones that can be expressed in a linear equation with lots of variables each with its own weight (the number that is multiplied times each variable).
