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.  Before that, I was a Master’s student at the Institute for Quantum Computing at the University of Waterloo.

I am coauthor of the textbook “Principles of Quantum Communication Theory: A Modern Approach”. The latest version can be found here. Please feel free to send feedback!

I am also a mentor for the QIT study group, which is part of the broader QWorld initiative.

  • 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).
