Bio-Sketch

Dr. Xiao Yuan received his Bachelor in theoretical physics from Peking University in 2012 and got his PhD in physics from Tsinghua University in 2016. Then he worked as an assistant researcher at University of Science and Technology of China in 2017, as a postdoc at Oxford University from 2017 to 2019, and as a postdoc at Stanford University from 2019 to 2020.  He is now an assistant professor at Center on Frontiers of Computing Studies, Peking University. My research interests focus on three aspects of quantum information science, including near-term and universal quantum computing, quantum foundation, and quantum cryptography.

Introduction

The Quantum Simulation and Quantum Information Lab was founded by Dr. Xiao Yuan in 2020 at Peking University, focusing on quantum simulation and computing algorithms and quantum information theory. We are currently focusing on three research directions:

•   Quantum computing
o    Quantum algorithms for NISQ and universal quantum computers
 Quantum error mitigation and quantum error correction
o  Benchmarking and optimization for realistic quantum hardware
•   Quantum foundation
o  Quantum resource theory
o  Coherence, entanglement, information scrambling, quantum channel   capacity
•   Quantum cryptography
o  Quantum random number generator
o    Quantum key distribution
