报告摘要: 
        An outstanding challenge of quantum computing is to build quantum devices with both excellent coherence and reliable universal control. Ancilla systems are often indispensable to universal control of a nearly isolated quantum system. However, ancilla systems are typically more vulnerable to environmental noise, which limits the performance of such ancilla-assisted quantum control. To address this challenge of ancilla-induced decoherence, we propose a general framework that integrates quantum control and quantum error correction, so that robust quantum gates resilient to ancilla noise can be achieved. We introduce the path independence criterion for fault-tolerant quantum gates against ancilla errors. As an example, we provide a path-independent gate for superconducting circuits with a hardware- efficient design, which has recently been experimentally implemented.

个人简介: 
        马稳龙博士从2010年起在中科院半导体李树深院士的指导下从事量子点、NV Centre等相关系统的自旋电子学研究,于2015年获得中国科学院大学的博士学位。求学期间获得所长奖学金、中心杰出研究生奖、三好学生等多项奖励。之后先后在香港中文大学刘仁保教授和耶鲁大学蒋良教授的研究组做博士后,继续自旋电子学的研究的同时也开始从事纠错量子计算的研究工作,随后跟随蒋良教授转到芝加哥大学继续博士后研究工作。在包括Phys. Rev. Lett.的PR系列、Nature Physics和Nature communication等高水平期刊上发表论文十六篇。
