Andrea W. Coladangelo

I am a postdoc at UC Berkeley and a Quantum Postdoctoral Fellow at the Simons Institute, advised by Umesh Vazirani.

Previously, I was a Research Fellow at the Simons Institute for the semester "the Quantum Wave in Computing". I received my PhD from Caltech in 2020, under the wonderful supervision of Thomas Vidick. Before that, I received a B.A. in Mathematics from the University of Oxford and a Master in Mathematics from the University of Cambridge.



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.

Since August 2020, I am an editor for the journal Quantum.

I am a co-founder of qBraid, a cloud-based platform for learning quantum computing
and developing quantum algorithms.


News: In Winter 2023, I'll be joining the University of Washington as an assistant professor in the Allen School of Computer Science and Engineering!
I'm on the lookout for PhD students to start in Fall 2023: feel free to write if you are interested!
