Ph.D. Student

Yale University


I am a PhD student at Yale University, and my research interests lie in quantum computing and computer security. I am currently working on quantum computer security, where I design attack and defense mechanisms on quantum computers and quantum cloud providers. I am also working on RTL design (Verilog) targeting FPGAs, where I implement Post-Quantum Cryptography (PQC) schemes that are secure under both classical and quantum computer attacks.

My Chinese name is 许传奇. The English translation of my Chinese first name is legend. If you are not sure about the pronunciation, you can call me legend :)
