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.
Crystal Senko

Crystal Senko was a graduate student in Chris Monroe's ion trapping group. While in the group she focused on ultrafast spin manipulation as well as quantum simulation of magnetism. She is now a postdoctoral researcher with Mikhail Lukin at Harvard. Senko is an undergraduate alumni of Duke University, where she worked with Dan Gauthier on magneto-optical trapping using distributed feedback lasers.
Xiaopeng Li

Xiapeng Li is a JQI Postdoctoral Fellow working in CMTC. His research interest is primarily in quantum condensed matter. His work covers novel states of matter in both well-controlled ultracold atomic systems and in complex electronic materials. He has been have been studying a broad range of systems, such as atomic p-orbital systems in optical lattices, dipolar quantum gases, and complex oxides. Some of his current efforts focus on (1) emergent spin orbital couplings and gauge fields in spinor Bose gases and Bose-Fermi mixtures as well as (2) band crossing and multi-orbital superconductivity, spin spirals and skyrmions in oxides and heterostructures. Li received his Ph.D. from the University of Pittsburgh and was an undergraduate at the University of Science and Technology of China, Hefei, Anhui, China.
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.
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.
Mohammad Hafezi

Hafezi is JQI fellow and works at the interface of condensed matter theory and quantum optics. The focus of his research is on theoretical and experimental investigations of artificial gauge fields and topological order in photonics systems. Such systems can be exploited as robust optical devices insensitive to disorder, which is the subject of his NSF Physics Frontier Center’s seed funding program. Moreover, in the presence of strong optical nonlinearity, such systems are expected to exhibit fractional quantum Hall physics, providing a platform for potentially observing anoynic statistics. He received his Ph.D. from Harvard in 2009 where he worked with Mikhail Lukin and Eugene Demler. There, he studied strongly correlated physics in AMO systems. In particular, he worked on the topological characterization of ultracold atoms in 2D and also non-equilibrium dynamics of strongly interacting photons in 1D.
