Hello I’m Xin-An Chen (陈信安). I joined the group as a PhD student in 2020. My general research interest is the interplay between quantum mechanics and information theory. For my PhD, I’m specifically focusing on processing quantum resources for information transmission. A few questions that I have thought about or am actively working on include:
- Single-particle coherence: It is well known that a quantum particle can be placed in a superposition of different spatial locations. Can we use this property to enhance information transmission? How much information can be mediated by a single quantum particle?
- Entanglement distillation and distribution: Many information processing tasks require high-fidelity quantum entanglement. However, various sources of noise deteriorate the quality of entanglement. How should we manipulate entangled states in the presence of noise? What are the fundamental limitations?
- Catalytic transformation of quantum resources: Catalysis are often used to facilitate chemical reactions. It can also be a powerful tool in quantum information theory as well. How can we use catalysis to facilitate transformations of quantum resources?
See google scholar for a list of my papers. Outside of research, I play too much football (dare I say the s-word?). I also like to read history, philosophy, and social sciences while enjoying 70s progressive rock. Here is a picture of me and my long-term collaborator.
