Mingyu Fan is a postdoctoral fellow in the Department of Physics, working with Professor Amar Vutha’s group. Fan received his PhD in physics from UC Santa Barbara and joined the University of Toronto as a Centre for Quantum Information and Quantum Control (CQIQC) Postdoctoral Fellow in August 2023.
What area of quantum information science do you research in?
I develop quantum sensors, which are devices that use the extreme sensitivity of quantum particles to measure tiny changes, using rare-earth ions embedded in crystals. By performing precise energy measurements of these ions, we can detect small fluctuations in the surrounding environment. These energy shifts may reveal new particles or interactions that have not yet been discovered.
What most attracts you to this field?
I am fascinated by the idea that precise measurements using a table-top apparatus can be used to study new physics. With quantum systems, we can detect extremely small signals and probe some of the same questions explored by high-energy particle collider experiments.
In your opinion, what are the most exciting applications that could come out of your area of research?
Quantum sensors developed for fundamental physics can also be used in real-world applications. For example, quantum magnetometers will allow us to obtain a more accurate magnetic map of the Earth, enabling future navigation without GPS. In addition, quantum gravimeters are useful for geological surveys and mineral exploration. These technologies will deepen our understanding of the environment and help build more resilient and sustainable infrastructure.
Why is it important to support, develop and fund quantum research right now?
We are at a stage where the quantum field begins to transition from fundamental research to transformative technologies. Continued support for quantum research ensures that we train the next generation of scientists and engineers while laying foundations for practical applications such as quantum sensing, quantum computing, and quantum networks.
What is the accomplishment that you’re most proud in your research?
I am most proud of building new precision-measurements platforms from the ground up across different quantum systems. Developing these new platforms is challenging, but it opens up new directions for discovering new physics using quantum technologies.
