取得的重要科研成果所获奖励

长期从事固态量子信息的理论研究研究领域包括量子退相干、量子控制、量子纠错和量子精密测量,取得了一系列理论创新成果,并吸引多个国际权威实验组的跟踪和合作研究:

1 揭示半导体自旋比特的退相干机制并提出了抑制自旋比特退相干的方法,相关理论发现被伦敦大学John Morton实验组验证,这为固态体系中的量子态保护提供了有力支撑(Phys. Rev. B 2015, 92, 161403(R); Nat. Commun. 2014, 5, 4822; Rep. Prog. Phys. 2017, 80, 016001)

2 提出了不依赖于路经的可容错量子操控原创理论,并被耶鲁大学Robert Schoelkopf 教授实验组在超导系统中完成实验验证,这为纠错量子计算的实现提供了创新方案 (Phys. Rev. Lett. 2020, 125, 110503; Nat. Phys. 2020, 16, 822)

3)提出利用半导体自旋比特退相干进行量子精密测量,并设计了一系列可有效提高量子精密测量效率的理论方案,这促进了固态体系在量子精密测量中的应用(Phys. Rev. Appl. 2016, 6, 054012; Phys. Rev. Appl. 2016, 6, 024019; Phys. Rev. Appl. 2016, 5, 044016);

4 提出了连续量子测量中的相变理论,可用于界定强测量和弱测量的边界,相关理论结果被中科院物理所潘新宇实验验证,这对量子精密测量和量子计算的测量方案设计具有重要的指导意义(Phys. Rev. A 2018, 98, 012117; Phys. Rev. Lett. 2017, 118, 150504)。

已发表论文18其中以第一或者通讯作者发表12篇,包括Nature PhysicsNature CommunicationsReports on Progresses in Physics, Science Bulletin各一篇Physical Review Letters 两篇,Physical Review A/B/Applied多次在国内外会议上做报告,包括在重大研究计划第二代量子体系的构筑和操控”2021研讨会上做邀请报告。 担任PRL, PRX, PRX Quantum, PRA, PRApplied, PRResearch等期刊审稿人。
