  • 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).
