About me

bio photo longMy name in simplified Chinese is 王鑫.

I am a Hartree Postdoctoral Fellow at the Joint Center for Quantum Information and Computer Science (QuICS) at the University of Maryland, College Park.

I received my doctorate in quantum information from the University of Technology Sydney (UTS:QSI) in 2018, under the supervision of Prof. Runyao Duan and Prof. Andreas Winter. I obtained my B.S. in mathematics (with Wu Yuzhang Honor) from Sichuan University in 2014.

My research aims to better understand the power and limits of information processing with quantum systems and the structure of quantum entanglement, which includes,

  • quantum Shannon theory
  • quantum entanglement and other quantum resource theories
  • magic states and fault-tolerant quantum computation
  • quantum networks
  • quantum programming language
  • connections of quantum computation and information to optimization, Markov chains, thermodynamics, and learning theory.

The overview of my research, the lists of my Publications and Presentations are available. Further information can be found in my curriculum vitae.
