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

Microsoft has introduced Majorana 1, a quantum chip with a "Topological Core" architecture, potentially enabling powerful quantum computers within years instead of decades. The breakthrough stems from a newly developed material called a topoconductor,

Major technological breakthroughs can, over time, create trillions in shareholder value. Quantum computing looks like one such possible opportunity, and Rigetti Computing (NASDAQ: RGTI) might be a good way to gain exposure to it. Quantum computing involves creating machines that process data in an entirely different way than traditional computers.

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

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.

Analysis pokes holes in protocol that underpins Microsoft’s claim to have created the first topological qubits.

I reported that Microsoft claims its new quantum chip is powered by an 'entirely new state of matter'. I said back then that I would leave it to the brainy big wigs to assess whether this new Majorana 1 chip actually represents the breakthrough that's been claimed.

Redmond insists it's got this right and has even more impressive results to share soon Updated Microsoft's claim of a quantum computing breakthrough has attracted strong criticism from scientists, though the software giant says its work is sound – and it will soon reveal data that proves it.
