# 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.

**Teaching**

I was a teaching assistant for the following courses at Caltech:

- (Fall 2018) CS152a: Introduction to Cryptography
- (Fall 2016) CS/Ph120: Quantum Cryptography (also offered as an EdX course)

Other teaching:

- I am an author of a quantum computing course for high school students, based on recorded video lectures, and programming exercises.
- (2018-2019) Muir High School, Pasadena: I tutored high school students in Math and Science as part of an outreach initiative of the Caltech Y Rise Program
- (2012-13) St. Andrew’s Primary School, Headington, Oxford: I ran the weekly chess club for students aged 6 to 10.
