Quanxin Mei
I'm a quantum physicist at HYQ Co., Ltd.currently working on trapped-ion quantum simulation and computing. My research focuses on using trapped ions to simulate quantum many-body physics and explore fundamental quantum phenomena.
I work extensively on implementing quantum simulations using trapped-ion systems, having demonstrated various important models like the Rabi-Hubbard model, Jaynes-Cummings-Hubbard model, and long-range transverse-field Ising model with up to 61 ions. I'm particularly interested in probing quantum phase transitions, non-Markovian dynamics, and critical phenomena through quantum simulation.
My recent work has led to several key advances in trapped-ion quantum computing, including the realization of multi-ion sympathetic cooling, observation of quantum superposition of topological defects, and implementation of individually addressed entangling gates in two-dimensional ion crystals. I collaborate closely with researchers at Tsinghua University's Center for Quantum Information to push the boundaries of what's possible with trapped-ion quantum systems.
