Microsoft says it has created a revolutionary computer chip that harnesses a new state of matter to pave the way for the most powerful quantum computers ever built.

The last two times Microsoft researchers claimed to have the topological qubit/quantum computer, their papers were criticized for being "incomplete and misrepresent[ing] the results" (see this summary, which already has the 2025 results mentioned), mostly failing to actually show any real evidence for Majorana modes. Personally, I'm holding out any excitement until this has gotten further or more widespread review from those with more expertise in this subject area.

The new chips will be fully self-aware and in their cold-fusion powered flying car, scheduled to be released in ten years.

 

Unless they offer an OS and compiler, I am out.

Vincent Mourik, a physicist at the Helmholtz Research Centre in Jülich, Germany, whose concerns helped to lead to the earlier retraction, is sceptical of the whole concept. “At a fundamental level, the approach of building a quantum computer based on topological Majorana qubits as it is pursed by Microsoft is not going to work.”

“As we perform more types of measurements, it will become harder to explain our results with non-topological models,” says Nayak. “There may not be one single moment when everyone will be convinced. But non-topological explanations will require more and more fine-tuning.”
