Update: Beginning in Spring 2026, the course will be offered under the new code ECE 544. Explore the mathematical methods and applications of quantum information. I have been teaching this exciting subject since 2018 and have had the pleasure of witnessing graduate students who took this course embark on successful research careers in quantum science…

Our paper has been recently published in Physical Review Applied. Emily Van Milligen (Wyant College of Optical Sciences, Univ. of Arizona), first author of our paper, wrote the following popular summary: Quantum networks have the potential to distribute entangled qubit pairs, typically photons, across vast distances, enabling breakthroughs in areas like long-baseline astronomy and distributed…

We work on one of the most well-known and important quantum sensing paradigms, that of sensing an optical phase. However, we consider the largely overlooked Bayesian approach. The literature on optical phase sensing in the frequentist approach (i.e., Fisher information approach) is vast, proving retrospectively the importance of said problem. In our work, we examine…
