This Small Quantum-Computing Firm Wants to Supercharge AI Startups

August 24, 2017

Berkeley-based quantum computing firm Rigetti will allow 40 machine learning startups from 11 countries to make use of its devices to help crunch their AI problems.

Rigetti is small compared to its main rivals—the likes of Google, IBM, and Intel. But as we’ve reported in the past, the firm is working on a complex chip architecture that promises to scale up well, and should be particularly suited to applications like machine learning and chemistry simulations. That’s why we made it one of our 50 Smartest Companies of 2017.

But, like IBM and Google, part of Rigetti’s business model has always been to develop a kind of quantum-powered cloud service that would allow people to make use of its technology remotely. The newly announced partnership—which will be with companies from Creative Destruction Lab, a Canadian incubator that focuses on science-based startups—is a chance to test that theory out using Rigetti’s Forest programming environment.

The Forest setup actually uses a combination of regular and quantum computing, allowing developers to write code of which only some is farmed out to quantum chips. The idea is to use its currently limited quantum resources as effectively as possible by throwing only calculations that will get the biggest speed boost on a quantum device towards Rigetti’s experimental chips.

"By pairing the two resources, you reduce the performance requirements of the quantum computer," Rigetti’s Madhav Thattai explains to MIT Technology Review. "Which means that even smaller, near-term devices can still be used for useful computation."

We are, of course, still a little ways off having a hulking quantum computer that can crunch the toughest of AI problems in a heartbeat. But many companies, Rigetti included, are now finally on the cusp of making practical quantum computers. And schemes like this will help prime future users of the hardware for a brave new quantum world.
