D-Wave Systems, Inc.  is a quantum computing company, based in Burnaby, British Columbia, Canada. D-Wave is the world's first company to sell quantum computers.
The D-Wave One was built on early prototypes such as D-Wave's Orion Quantum Computer. The prototype was a 16-qubit quantum annealingprocessor, demonstrated on February 13, 2007 at the Computer History Museum in Mountain View, California. D-Wave demonstrated what they claimed to be a 28-qubit quantum annealing processor on November 12, 2007. The chip was fabricated at the NASA Jet Propulsion LaboratoryMicrodevices Lab in Pasadena, California.
The underlying ideas for the D-Wave approach arose from experimental results in condensed matter physics, and in particular work on quantum annealing in magnets performed by Dr. Gabriel Aeppli. These ideas were later recast in the language of quantum computation by MIT physicists Ed Farhi, Seth Lloyd, Terry Orlando and Bill Kaminsky, whose publications in 2000 and 2004  provided both a theoretical model for quantum computation that fit with the earlier work in quantum magnetism (specifically the adiabatic quantum computing model and quantum annealing, its finite temperature variant), and a specific enablement of that idea using superconducting flux qubits which is a close cousin to the designs D-Wave produced. In order to understand the origins of much of the controversy around the D-Wave approach, it is important to note that the origins of the D-Wave approach to quantum computation arose not from the conventional quantum information field, but from experimental condensed matter physics.
On May 11, 2011, D-Wave Systems announced D-Wave One, described as "the world's first commercially available quantum computer", operating on a 128-qubit chipset using quantum annealing (a general method for finding the global minimum of a function by a process using quantum fluctuations) to solve optimization problems. In May 2013, a collaboration between NASA, Google and the Universities Space Research Association (USRA) launched a Quantum Artificial Intelligence Lab based on the D-Wave Two 512-qubit quantum computer that would be used for research into machine learning, among other fields of study.
On August 20, 2015, D-Wave Systems announced the general availability of the D-Wave 2X system, a 1000+ qubit quantum computer. This was followed by an announcement on September 28, 2015 that it had been installed at the Quantum Artificial Intelligence Lab at NASA Ames Research Center.
In January 2017, D-Wave has released the D-Wave 2000Q and Qbsolv. Qbsolv is a piece of open-source software that solves QUBO problems on both company's quantum processors and classic hardware architectures.
