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 (discrete-variable and continuous-variable). My advisor is Victor V. Albert and Mohammad Hafezi.

Research areas:

• Intersection of quantum information and quantum matters
• Quantum information on both physics and computer science sides, quantum simulation algorithms, continuous-variable quantum systems, quantum error correction
