Scientist

Welcome!

I'm Hilary Hurst and I am an Assistant Professor of Physics at San José State University. I'm a quantum educator and theoretical physics researcher, with broad interests many-body atomic physics and quantum information science, including

  • theory of quantum measurement and feedback control for many-body quantum systems
  • noise mitigation and characterization in open quantum systems
  • dynamics of spinor Bose-Einstein condensates under continuous measurement
  • control of topological defects - magnetic skyrmions and vortices - in ultracold atomic systems

Opening up the quantum world. One of the most counter-intuitive aspects of quantum mechanics is the effect that measurement has on a quantum system. Just by looking at a quantum system (measuring it), an observer can affect the outcome of an experiment. This can often be detrimental to experimental outcomes, but there are situations in which it can actually be helpful. One such situation is in using results from quantum measurement to perform feedback control, thereby changing state of the quantum system in real-time. Quantum feedback control can be particularly tricky, because any disturbance to the system can affect entanglement and coherence - both key quantum properties for computation.

In my research, I study the problem of robust quantum feedback control in a variety of ways. I seeks to understand how noise and dissipation affects quantum systems, and I also explore how to use weak measurement as a tool to control quantum systems without completely opening them up to the environment. I develop quantum control methods and theories specific to many-body systems, which can have their own complicated internal dynamics. I use a variety of analytical and numerical tools in my theoretical research and I collaborate closely with experimental groups.

About Me

I grew up in Greeley, Colorado and received a Bachelor's degree in Engineering Physics from the Colorado School of Mines (CSM) with a minor in Public Policy. I am an All-American track and field athlete and was awarded the Senior Scholar-Athlete Award upon graduating from CSM. I then traveled abroad to earn a Masters in Applied Mathematics & Theoretical Physics at the University of Cambridge, where I was a member of Wolfson college and rower for the Wolfson W1 women's eight. I moved back to the US to complete a PhD, and I received my degree in theoretical condensed matter physics from the University of Maryland under the supervision of Prof. Victor Galitski. My dissertation focused on the dynamics of topological defects in hybrid quantum systems. While I was a graduate student at Maryland I served as Event Coordinator for Women in Physics and was the physics department representative to Graduate Student Government. Following my PhD I was a National Research Council (NRC) Postdoctoral Fellow at NIST and the Joint Quantum Institute in the group of Ian Spielman , focusing on the theory of quantum measurement and feedback control for many-body systems. I joined San José State University in Fall 2020 as an Assistant Professor of physics. SJSU is the largest public university in Silicon Valley and a founding campus of the California State University system.

Outside of physics, I enjoy cooking, reading novels, and staying active. I love being outdoors and you can often find me running, doing yoga, or hiking with my husband and our hound dog Leia. I am an avid traveler (when it is safe to do so), and I have visited over 25 countries on 6 of the 7 continents. My profile picture was taken on a trip to Greenland in 2019.
