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, 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.


My research interests are broadly in quantum computation, with a focus on quantum cryptography. I am particularly interested in understanding what cryptographic tasks can be realized using quantum information, and under what assumptions. I was previously very interested in foundational questions about entanglement and quantum correlations inspired by the topic 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.
