I’m a Postdoctoral Researcher at Freie Universität Berlin in the group of Jens Eisert.
I did my PhD in the Quantum Science and Technologies Group in the Hearne Institute for Theoretical Physics at Louisiana State University. Previously, I was a Master’s student at the Institute for Quantum Computing at the University of Waterloo.
My research is in the general area of quantum information theory. For the past couple of years my focus has been on quantum networks as well as quantum computing; specifically, for the latter, applying machine learning methods to quantum algorithms for near-term applications. In the past, I worked on quantum cryptography, specifically quantum key distribution.
I am coauthor of the book “Principles of Quantum Communication Theory: A Modern Approach” with Mark Wilde. A preliminary version can be found here; see also the arXiv version. Please feel free to send feedback!
- Check out my research for details on what I’ve been working on, as well as my Google Scholar page and my papers on arXiv.
- My talks can be found here.
- My github page contains the package QuTIpy, which is a Python package for performing quantum information calculations, as well as code that I have written for my various research projects.
- I’ve also compiled a list of introductory resources on the topics pertaining to my research and to physics in general.
- See this How Stuff Works article, in which I talk about the future quantum internet. See also this article, written for a broad audience, for an introduction to the quantum internet. I also give a general talk about the quantum internet here (slides here).
