A physicist questions Microsoft's claim of achieving topological qubits, citing flaws in their testing method for key quasiparticles, Majoranas. Announced on February 19 without peer-reviewed support, the claims have faced skepticism. Microsoft's subsequent communications do not address the scientific concerns, leading to further scrutiny from experts like Henry Legg, who argues that the foundation for their claim is compromised. Despite the criticism, Microsoft's team asserts their standing by the claims made, marking ongoing tension between innovation and validation in quantum computing.
"Since the TGP is flawed, the very foundations of the qubit are not there," says Legg, highlighting critical doubts over Microsoft's topological qubit claims.
"The criticism can be summarized as Legg constructing a false straw man of our paper and then attacking that," responds Nayak, defending Microsoft's stance.
