导读: 第七届两年一度的贝尔奖 (John Stewart Bell Prize) 颁发,以表彰在量子力学基本问题及其应用研究方面做出特殊贡献的科学家[1]。此次奖授予John Martinis (前谷歌量子计算负责人,以下简称“Martinis”),以表彰他在超导装置设计和控制方面的创新,特别是他在设计低误差多量子比特超导芯片方面的领导才能,他带领谷歌首次令人信服地实现了量子优势,开启了计算技术的新时代。
不过遗憾的是,Martinis带领团队获得成就之后,并没有继续在谷歌的工作。这位帮助谷歌实现“量子霸权”的关键人物已在悉尼重新露面,并在澳大利亚初创公司,硅量子计算公司 (SQC) 任职,担任重要角色。图5|任职于SQC的John Martinis和Michelle Simmons(来源:SQC)未来,硅量子计算能否大放光彩呢,期待。引用:[1]https://cqiqc.physics.utoronto.ca/bell-prize/bell-prize-winners/john-martinis-awarded-the-seventh-bell-prize/[2]J.M.
