Microsoft's announcement of a breakthrough in quantum computing faces skepticism from physicists, who say evidence supporting the company's claims remains insufficient.The tech giant reported creating Majorana particles- a development it says could revolutionize quantum computing - but the accompanying peer-reviewed paper in Nature does not conclusively demonstrate this achievement, according to multiple quantum physics experts who reviewed the research. Microsoft's corporate vice president for quantum hardware, Chetan Nayak, acknowledged the Nature paper wasn't meant to prove the particles' existence, though he claimed measurements suggested "95% likelihood" of topological activity. "This is where you cross over from the realm of science to advertising," said Jay Sau, a theoretical physicist at the University of Maryland who sometimes consults for Microsoft but wasn't involved in the current research.
