Recent progress on noisy intermediate-scale quantum (NISQ) devices opens up exciting new opportunities for quantum many-body physics. The unprecedented level of control and measurement capabilities of NISQ platforms makes them not only candidates for quantum computers, but also an excellent laboratory to explore interesting physics ranging from non-equilibrium dynamics of closed or open quantum systems, to emulating nontrivial phases of matter. In this talk, I will present several works along this line of research. I will first talk about entanglement phase transitions, which are often hallmarks of dynamical phase transitions in many-body systems. I will discuss two different setups where such entanglement phase transitions occur, and yet are of distinct nature. Then, I will demonstrate a mechanism for weak ergodicity breaking in quantum systems, which is known as Hilbert-space fragmentation. Finally, I will show how one can emulate nontrivial phases of matter on near-term devices using the example of Z₂ and Z₃ topological quantum spin liquids. 
 

I did my undergraduate studies at Peking University from 2009 to 2013. Then I went to graduate school at Boston University, where I worked with Prof. Claudio Chamon. After obtaining my Ph.D. degree in 2019, I joined University of Maryland College Park as a Postdoctoral Researcher in Prof. Alexey Gorshkov's group.
