Patrick Rall's Homepage

I am a Research Staff Member at the IBM Quantum. I work at the MIT-IBM Watson AI Lab in Cambridge, MA.

I obtained my PhD in Physics from the University of Texas at Austin in 2021 where I was advised by Scott Aaronson. Prior to that I completed my undergraduate studies at the California Institute of Technology where I studied Physics and Computer Science under John Preskill.
