Microsoft's quantum leader shrugs off scientific skepticism over Majorana claims

Zulfi Alam, Microsoft’s corporate vice president of quantum, expressed indifference toward the scientific community’s doubts about his group’s Majorana quasiparticle breakthrough. The claim, made last year, was met with skepticism because the supporting data were deemed inconclusive and the work had not undergone peer review. Microsoft’s earlier Nature paper on Majorana evidence was withdrawn after independent physicists highlighted analytical flaws.

In June, the firm announced a qubit claimed to be 1,000 times more reliable, yet it still withholds the underlying data, arguing that commercial concerns and the slow pace of academic publishing make disclosure impractical. Trevor Lanting of D-Wave Quantum warned that dismissing peer review often signals weak results. Despite the criticism, Microsoft maintains its target of delivering a functional quantum computer by 2029, with Alam saying the pushback only fuels a faster drive toward a working machine.
