Quantum sensing and quantum many-body theory.
Hi!
I’m Lev, a physics Ph.D. student at Boston College in Professor Benedetta Flebus’s group, working at the intersection of quantum sensing and quantum many-body theory. I graduated from Harvey Mudd College in 2026 with a B.S. in Joint Mathematics and Physics (High Distinction, Honors in Physics), where I researched adaptive entanglement witnessing with Professor Theresa Lynn, and I have interned at MITRE in quantum theory and integrated photonics.
Outside of physics, I directed HMC’s New Student Orientation, founded the HMC Simulation Racing Club, and played outside hitter for the Claremont men’s club volleyball team. Feel free to reach out at lev.gruber@bc.edu.
Research
Quantum Theory & Quantum Memories Intern, MITRE
Theory and simulation for quantum memories and integrated photonics.
Quantum Optics Group (Lynn Lab), Harvey Mudd College
Senior thesis and experiments on adaptive entanglement witnessing: certifying that an unknown two-photon state is entangled using far fewer measurements than full state tomography. Awarded HMC’s Thomas B. Brown Memorial Award for Senior Research in Physics.
Quantum Materials and Nanodevice Laboratory, San Francisco State University
Fabricated monolayer MoS2 samples in ambient and glove box conditions and used Raman spectroscopy to show how the preparation environment changes their vibrational modes.
