Google has recently announced the fruits of their research with D-Wave, a firm that claims they have built the first quantum computer. Hartmut Neven, Head of Google's Image Recognition team, announced they have been able to successfully sort 20,000 images into sets with and without automobiles faster than anything running in a Google data center currently.
The team adapted quantum adiabatic algorithms to the task and trained on a set of 20,000 human tagged images and video stills of street scenes with and without automobiles.
Perhaps we can look to the future of quantum computing to untangle the problem of relevance and high quality search.
