Researchers have criticised Microsoft's new Majorana 1 quantum computer, saying the company has made claims about the way it works that aren't fully backed up by scientific evidence

France's Pasqal has made its neutral-atom quantum computing technology available via the Microsoft Azure Quantum cloud service. According to the company, it is the first neutral-atom quantum computer to be offered via Microsoft.

Several physicists say the lack of a peer-reviewed, detailed paper on Microsoft's work undermines its claims. The tech community is also skeptical.

To the best of my woefully scientifically underequipped knowledge, Microsoft's new quantum chip supposedly uses Majorana fermions, a kind of theorised and apparently newly discovered emergent particle that's indistinguishable from its antiparticle, a fact that is supposed to help improve qubit stability.
