D-Wave One Rainier uses quantum annealing to solve optimization problems. The D-Wave One was claimed to be the world's first commercially available quantum computer system. Its price was quoted at approximately US$10,000,000.

D-Wave is the only quantum computing company solving real business problems and demonstrating quantum ROI.

D-Wave systems use a process called quantum annealing to search for solutions to a problem. In nature, physical systems tend to evolve toward their lowest energy state: objects slide down hills, hot things cool down, and so on. This behavior also applies to quantum systems.

Can You Buy a Quantum Computer? Yes, it's possible to buy a quantum computer in 2023. However, quantum computers are not yet widely available to the general public and are currently very expensive and extremely difficult to manufacture.
