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.
Ryan Barnett

Ryan Barnett, a former JQI postdoctoral fellow at the Condensed Matter Theory Center (CMTC), is now a ‘Lecturer in Condensed Matter Theory’ (UK equivalent of assistant professor) at Imperial College in London. Ryan is a theoretical physicist interested in collective effects in ultracold atomic gases. While at the JQI his research focused on spinor condensates, non-equilibrium dynamics, and synthetic gauge fields. Much of his recent work at CMTC was motivated by ongoing experimental activities at the JQI.
Gretchen Campbell

Campbell is a NIST JQI fellow and works in the Laser Cooling and Trapping group. In her atom circuits lab, reserachers probe Na BECs in toroidal traps. The goals of these experiments include studying superfluidity, as well as superfluid analogs to superconducting circuits. A second experiment with ultracold strontium is being built. She received a Ph.D from MIT in 2006, where she worked with Wolfgang Ketterle and Dave Pritchard. There, she used Rb BECs in optical lattices to study atom interferometry, nonlinear atom optics and the superfluid – Mott insulator phase transition. These experiments included the first direct observation of the atomic recoil momentum in dispersive media. More recently, she worked with Jun Ye on precision measurements and frequency metrology with an ⁸⁷Sr optical lattice clock.
Shantanu Debnath

Shantanu Debnath is a graduate student in Chris Monroe's trapped ion quantum information group. He earned an undergraduate degree in engineering physics from the Indian Institute of Technology-Mumbai and afterward briefly studied the correlations that arise in 3- and 4-qubit entangled quantum states. As a PhD student at JQI, he has helped develop a 5-qubit trapped ion quantum computer that a user can program with any sequence of logic gates. This software-defined connectivity of many qubits opens up the possibility of executing large-scale quantum algorithms and simulations.
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.
David Hucul

David Hucul is a graduate student in Professor Chris Monroe's trapped ion quantum information lab at the Joint Quantum Institute. He earned undergraduate degrees in physics and chemistry in 2006 from the University of Michigan and a master's degree at MIT in 2009 under Wolfgang Ketterle. David started his PhD work with Chris Monroe in 2009 working on using frequency combs to entangle trapped ions. He now works on entangling trapped atoms within and between ion traps using both phonons and photons to create quantum networks. He expects to finish his graduate studies sometime in 2015 and hopes to find a postdoctoral position after that.
