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.

Four decades ago, physicists were theorizing that the mind-bending mechanics of quantum physics could be harnessed to make a new kind of computer that’s exponentially more powerful than conventional machines.

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.

A peer-reviewed critique of Majorana 1 claims Microsoft did not conclusively demonstrate a working topological qubit. Microsoft disagrees.

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

The White House has issued an executive order aiming to unify and accelerate U.S. development of quantum technologies, including space systems that could enable next-generation navigation, sensing and secure communications.

A critique from the University of St Andrews published in the journal Nature provides evidence that Microsoft's claimed quantum computing "breakthrough" was built on flawed foundations.

The alleged dangers of AI have been shoved down people’s throats for years, led by doomerism about it eliminating human jobs or wiping out mankind itself. Yet, there are far fewer discussions about how scientists are on the cusp of a breakthrough more powerful and much more worrying: Quantum computing.
