D-Wave, based in British Columbia, is the only company in the world currently offering a functioning quantum computer. They have sold systems, which run in the range of $10 million per computer, to three customers: Lockheed Martin, Google and the Los Alamos national laboratory. Currently the Navy and other government agencies are renting time on D-Wave owned computers.
There is massive potential for DWave systems to help with Big data problems, machine learning and optimization of logistics efforts. The US government and military would save a lot of money with improved logistics. It could also help with big-picture design issues such as scheduling the most efficient constellation for a network of satellites to capture imagery around the world. Machine learning can be used to train autonomous systems.
