此前，Diraq与imec已展示，利用常规半导体工艺制造的量子比特在执行单比特操作时，保真度可达 99.9%。然而，要支撑真正的量子计算能力，还必须在双比特操作中实现高保真度。此次突破正是填补 了这一关键空白。 祖拉克表示，最新成果为开发完全容错、功能完善且具备成本效益的量子计算机扫清了道路。 （文章来源：科技日报） 研究团队在论文中指出，由Diraq设计、imec制造的器件，在执行涉及两个量子比特的逻辑操作时，保 真度超过99%。双比特逻辑门是量子计算的基本构件，其可靠性被视为量子计算机走向大规模容错的关 键指标。 美国国防高级研究计划局正在推进"量子基准计划"，要求包括Diraq在内的18家公司证明能否达到"实用 规模"目标。所谓"实用规模"，是指量子计算机在商业价值上超过其运行成本。专家认为，实现这一水 平至少需要在芯片上稳定操控数百万量子比特，以抵消量子态极易出错的弱点。 祖拉克介绍说，此次成果表明，硅基量子芯片可依托现有CMOS工艺进行大规模制造，从而在降低成本 的同时实现高保真度，为研制数百万比特级量子计算机开辟了可行路径。 据新一期《自然》杂志报道，澳大利亚新南威尔士大学的量子技术初创公司Dir ...
