People Profiles

James R. Williams

James R. Williams is a JQI Fellow and assistant professor of physics, and his chief area of research is experimental condensed matter physics. Specifically, he specializes in understanding why certain one and two-dimensional materials (e.g. topological insulators, graphene) depart from normal conductivity provided by free electrons. Dr. Williams received his bachelors in engineering physics at Santa Clara University. He then went on to get his MS and PhD from Harvard University in 2009 on the subject of grapheme, while studying under Charles M. Marcus. He was then a postdoctoral fellow at Stanford before coming to Maryland.
Mohammad Maghrebi

Mohammad Maghrebi earned his PhD in physics at the Massachusetts Institute of Technology, where he received the Sergio Vazquez Prize for his research on quantum fluctuations. For his postdoctoral research at JQI, he is working towards understanding non-equilibrium phases of matter in hopes of creating states of matter that do not occur outside the lab. He is also working on quantifying entanglement of many-body systems in equilibrium as well as finding patterns of entanglement generation outside of equilibrium.
Phil Richerme

Phil Richerme is a postdoc in Chris Monroe's Trapped Ion Quantum Information Group. He studies quantum magnetism using a well-controlled and well-isolated system of atomic ion spins, realizing Feynman's original proposal for a quantum simulator. These experiments probe the ground state and dynamical evolution of interacting spin systems, which are difficult (or impossible) for classical computers to calculate for even a few dozen spins. Phil received his Ph.D. from Harvard in 2012, working with Gerald Gabrielse and the ATRAP collaboration at CERN to trap antihydrogen atoms for sensitive tests of CPT symmetry.
Nicholas Grabon

Nicholas Grabon is a JQI graduate fellow who received an undergraduate degree in physics at the University of Wisconsin-Madison. There, he helped design silicon chips with embedded quantum logic. At JQI, he previously worked on the theory of topological states on a lattice containing individual sites. Now, he is working with Vladimir Manucharyan to build smaller resonators with higher quality, design (fluxonium) qubits with decreased noise and better understand many-body physics.
Alexander Craddock

Alexander Craddock is a PhD student at JQI who earned a Bachelor and Master degree in physics at University College London. As an undergraduate student, he studied whether a commercial device from D-Wave behaved like a quantum computer. After doing master’s work in high-energy physics, his focus shifted back to quantum information. Now he works in Steve Rolston and Trey Porto’s interacting photons group which hopes to one day develop a quantum repeater, a device to allow long distance quantum communication, using Rydberg atoms.
Efim Rozenbaum

Efim Rozenbaum is a graduate fellow at JQI who studied physics as an undergraduate and graduate student at St. Petersburg State University. His undergraduate thesis focused on new numerical methods for solving the equations that govern quantum systems with axial symmetry, and his Master’s thesis continued this work for highly charged heavy ions. Now, he works with JQI and the Condensed Matter Theory Center to study the effect of interactions on dynamical localization, the signatures of chaotic transitions in quantum dynamics and non-Markovian soliton dynamics with non-Ohmic friction.
