Quantum computing is now emerging as a rapidly-growing industry on a global scale. This is mainly because of the many technological breakthroughs achieved over the last few years. Remarkably, it was experimentally demonstrated that the status of computational advantage (also known as quantum supremacy) can be reached with only 53 noisy qubits. The next step is to demonstrate how near-term chips can solve practical problems better than any classical means. For this purpose, hardware improvement is not enough; what is perhaps more important might be the algorithm and/or software part. In this talk, I will share my experience over the last few years in trying to push forward this direction.

I am currently an associate professor at the physics department of SUSTech, Southern University of Science and Technology (南方科技大学) , which is located in the city Shenzhen (深圳) of China. I am interested in many areas in physics, chemistry, and information science. Recently, I am focusing on research problems in quantum information science, which is highly interdisciplinary and emerging rapidly as a new field of science.The goal of quantum information science is to rethink about many questions in quantum physics from the point of view of information science,and vice versa. Ultimately, we will be able to not only understand quantum physics better but also know how to dramatically improve the ways of information processing.
