Overview of Academic Research
Prof. Xu’s research interest is photonic quantum computing and quantum simulation. His work focuses on constructing photonic tensor network states, implementing quantum variational algorithms and quantum approximate optimization algorithms, and advancing the application of photonic quantum information processing technologies to real-world problems. He aims to achieve scalable photonic quantum walks for quantum simulations of both equilibrium and non-equilibrium many-body physics, such as topological states of matter, dynamical quantum phase transitions, and quantum thermalization. Additionally, he investigates fundamental questions in quantum measurement, including quantum weak measurements and weak values, quantum non-invasive measurements, and interaction-free quantum measurements, while exploring their applications in quantum information. Relevant achievements have been published in journals including Nature Physics, Nature Photonics, and Physical Review Letters.
