Google and XPRIZE collaboratively introduce $5 million reward to identify practical uses for quantum computers

Google and XPRIZE are launching a $5 million competition to create a quantum computer that could actually benefit society. It’s already known that quantum computers can perform certain tasks faster than classical computers, ever since Google first claimed the quantum benefits of its Sycamore processor in 2019. However, these demonstration tasks are simple benchmarks and have no real-world applications.

“There are a lot of fairly abstract mathematical problems for which quantum computers can prove to provide very significant speedups,” he says. Ryan Babush Google. “However, much of the research community is less focused on adapting more abstract quantum acceleration to concrete real-world applications, or on trying to figure out how quantum computers can be used. I didn’t.”

To this end, Google and the XPRIZE Foundation are inviting researchers to come up with new quantum algorithms as part of a three-year competition. The winning algorithm could potentially solve an existing problem, such as finding a new battery electrolyte that significantly increases storage capacity, but it doesn’t have to actually solve the problem, Babush said. Instead, researchers only need to demonstrate how the algorithm is applied and detail the exact specifications of the quantum computing required. Alternatively, competitors could demonstrate how existing quantum algorithms can be applied to real-world problems that have not been considered before.

The award examines how big an impact an entrant’s algorithm can have, whether it tackles problems similar to those outlined in the United Nations’ Sustainable Development Goals, and how well it can be done on available machines. They will be judged on a variety of criteria, including feasibility. Now or in the near future.

The $5 million prize pool consists of a $3 million grand prize to be split between up to three winners, $1 million to five runners-up, and $50,000 each to the 20 semi-finalists. .

The award could help shift the focus of quantum computing researchers from technical definitions of quantum benefits, such as those demonstrated by Google and IBM, to real-world applications, it said. Nicholas Quesada At the Polytechnic University of Montreal, Canada. “[The prize is] “We realized clearly that this is a very important issue,” Quesada said. “We need to think about what we’re going to do with quantum computers.”

But finding socially beneficial quantum algorithms requires a deeper understanding of how quantum computers work, including how they deal with noise and errors, he said. bill fefferman at the University of Chicago. The award does not address this fundamental aspect of building quantum computers, he says.

“I’m generally very optimistic that we’ll find an algorithm that’s really useful,” Pfefferman says. “I’m not very optimistic that within the next three years we’ll be able to discover those algorithms and implement them on the current hardware that’s going to exist.”
