Title: Spin Quantum Coherent Control and Its Application
The science of quantum control lies at the heart of modern physics. Various applications of quantum control have emerged and we witness great development in recent years, such as quantum computation, quantum simulation, and quantum metrology, etc. Spins of electrons and nuclei are among the most promising physical systems that can realize reliable and robust quantum control. They have a major advantage since the quantum coherence can be protected very eﬃciently against external noise, which represents the main challenge to the large-scale implementation of quantum control.
This presentation will mainly focus on our recent experimental study of quantum control over spins in solids. We concern on several respects such as decoherence suppressing with dynamical decoupling, precise spin control, eﬃcient realization of quantum algorithms and simulation, and ultrasensitive sensing with single spins in diamond.

Prof. Du is an expert in the area of spin quantum physics and its applications. He has developed a series of advanced spin quantum control methods to precisely manipulate spin quantum states and preserve its quantum coherence. Based on these, he achieved fruitful scientiﬁc achievements on quantum computation, quantum simulation, and quantum metrology, including the ﬁrst observation of single-protein spin resonance spectroscopy under ambient conditions. So far he has published more than 170 scientiﬁc papers, including 45 papers published in Nature, Science, Nature Physics, Nature Communications, and Physical Review Letters. His research achievements have received the second prize of 2012 National Natural Science Award, The Outstanding Achievements in Natural Science by the Ministry of Education of China (2011), The Huang Kun Award of Solid-state Physics and Semiconductor Physics from Chinese Physical Society (2011), and The Award in Basic Science from Zhou GuangZhao Foundation (2016).
