Microsoft’s claims of major breakthroughs in quantum computing have been challenged by UK-based physicist Dr Henry Legg. In a paper published in Nature, he argues that the software tool used by Microsoft contained coding errors and was not sufficiently accurate.
The tech giant has invested heavily in building a quantum computer, which operates differently from traditional machines and is said to solve complex global challenges too difficult for current supercomputers. However, Legg contends that it's still unproven whether Microsoft can create the theoretical Majorana particle that underpins its approach.
Microsoft stands by its results, stating that scepticism and rigour are part of the scientific process. The company claims to be sharing data with Darpa for independent arbitration but some information remains commercially sensitive.
The quest for a reliable quantum compute is an industry-wide challenge. Despite retracted claims in 2021, Microsoft continues to pursue its unique approach based on a 90-year-old physics theory and state of matter that defies classification as solid, liquid or gas.
