The improvement stems from a new material stack and tighter control of Majorana fermion states, according to the firm’s research brief. Microsoft plans to ship the first batch to its quantum cloud partners later this year.\n\nIf the error‑rate claim holds up, developers could run deeper algorithms before decoherence forces a reset, nudging quantum computers closer to solving real‑world problems like materials simulation. The step also backs Microsoft’s bet on topological qubits as a viable path amid competing superconducting approaches.\n\nSkeptics will watch early benchmark runs closely; past claims about Majorana 1 drew heavy criticism, and the industry still lacks a universally accepted error‑rate baseline for topological devices.","[\"quantum computing\",\"microsoft\",\"hardware\"]","2026-06-02T18:15:00.000Z","2026-06-02T19:10:59.748Z","2026-06-05T16:22:29.171Z","published",null,[],[25,26,27],"quantum computing","microsoft","hardware",[29],{"name":30,"url":31},"The Verge","https:\u002F\u002Fwww.theverge.com\u002Fnews\u002F940874\u002Fmicrosoft-majorana-2-quantum-chip-build",0]
