Google is looking at quantum computing to help it sort through the millions of searches it conducts daily, and it's working with processors from Canadian company D-Wave. Quantum computing will help Google with the sophisticated artificial intelligence technologies such as machine learning and pattern recognition that its services are based on. Solving the more difficult problems inherent in machine learning and pattern recognition using more conventional methods would require server farms so large that they could never realistically be built.
One correction: D-Wave DOES NOT use the "unconventional D-Wave superconductors". The company name "D-Wave" is historical, going back to the times it was started in 1999. For quite a while now we are using very conventional, Low-Tc Nb/Al-AlOx superconductors.
