Doctoral Student at JQI and QuICS

Curriculum Vitae


I am a graduate student at Joint Quantum Instiute and 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 advisors are Victor V. Albert and Mohammad Hafezi.
