Jiahui Liu
I am a Senior Researcher in quantum computing at Fujitsu Research.
Before joining Fujitsu, I was a postdoctoral researcher at Massachusetts Institute of Technology, hosted by Prof. Vinod Vaikuntanathan and Prof. Ran Canetti.
I'm interested in quantum computing, cryptography and general theoretical computer science.
Education:
I obtained my PhD degree in computer science from the University of Texas at Austin, advised by Prof. Scott Aaronson.
Before coming to UT Austin, I obtained my bachelor degree in computer science at Columbia University.
