A new Nature critique questions Microsoft’s quantum computing research, raising doubts about a key study behind its goal of building a working quantum computer by 2029.

In a laboratory in Broomfield, Colorado, 98 atoms are suspended in midair, held in place by electric fields and cooled to temperatures close to absolute zero.

By Stephen Nellis SAN FRANCISCO, June 24 (Reuters) - A new critique in the scientific journal Nature is raising fresh questions about Microsoft's claimed quantum computing breakthrough last year, which underpinned the company's announcement this month that it will have a working quantum system by 2029.

Quantum computing firm QuEra says it plans to make a fault-tolerant quantum computer and offer it to users through the cloud in 2028, which will require a real leap in engineering

The company has been touting its quantum technology for years, but some experts say these claims just don’t pass muster

The city is betting on a promising—but commercially unproven—technology.

The point at which quantum computers outperform classical ones will arrive. The question is who controls the infrastructure when it does.

Amazon's AI chief says the first commercially useful quantum computer is just five to seven years away. Here is what that means for investors and the tech industry.

The executive orders prioritize investments in quantum sensing, networking, workforce development and domestic supply chains.
