I am a graduate student at Joint Center for Quantum Information and Computer Science. My research interest is quantum information and quantum error correction. For discrete-variable systems, I am interested in topological error-correcting codes and their relation to topological orders. For continuous-variable systems, I am interested in stabilizer codes and operations defined on Lie group quantum systems, including oscillator and rotor codes. My advisor is Victor V. Albert.
Research interests:
- Algebraic construction of stabilizer codes
- Topological codes
