周三，微软低开低走，盘中跌3%。消息面上，微软在Build 2026开发者大会上发布第二代拓扑量子芯片Majorana 2，声称其量子比特平均存活时间突破20秒，较前代提升逾1000倍；同时宣布将可扩展实用型量子计算机的路线图提前至2029年。然而，这一高调宣布却遭多位物理学家公开质疑，直指其技术从未成功。
圣安德鲁斯大学理论物理学家亨利·莱格的批评称，微软仅展示了单个设备上的少数数据，未提供多设备可重复性的公开证据，若没有独立的验证，就不能排除这是偶然的伪造成果。
多位业内专家提出，微软此番公布的研发进展没能通过基础科学核验，其宣称的研发提速依托未完成严谨验证的实验数据，相关结论难以获得行业认可。
