Andrea Coladangelo

I am an assistant professor at the University of Washington, Seattle since January 2023, where I co-lead the Quantum group at the Allen School of Computer Science & Engineering. I am also part of the Theory and Crypto groups.


I am broadly interested in quantum computation. Recently, I have been most excited about understanding the interplay between quantum computation and cryptography. Previously, I have studied foundational questions about entanglement and quantum correlations, inspired by the question of certifying quantum devices. 

Short Bio: Before UW, I was a postdoctoral researcher at UC Berkeley and the Simons Institute, working with Umesh Vazirani. I obtained my PhD at Caltech, where I was fortunate to be advised by Thomas Vidick. In a previous life, I received a B.A. in Mathematics from the University of Oxford and a Master in Mathematics from the University of Cambridge. I co-founded qBraid, a cloud-based platform for learning quantum computing and developing quantum algorithms.
