People Profiles

Wes Campbell

Wes Campbell is a JQI alumni and now a faculty member at UCLA where his group studies cold molecules and trapped ions. His cold molecule research is an outgrowth of the NSF Physics Frontier Center’s seed funding program, here at JQI. While at JQI, Wes did research in Chris Monroe’s trapped ion quantum information group. Wes was instrumental in constructing an experiment that focuses on ultrafast gates with ions. Later in his postdoc, he worked on quantum simulations of magnetism with ion chains. More about his current group at http://campbellgroup.physics.ucla.edu/
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.
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.
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.
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.
Aftaab Dewan

Aftaab Dewan, a graduate fellow at JQI, received undergraduate degrees in physics and mathematics at Amherst College. There, he was a recipient of the Bassett Prize and the Stifler Prize, and conducted research on studying dynamics of Bose-Einstein Condensates. His senior thesis examined how neutrinos scatter off of materials such as lead or glass. He now works with Steve Rolston to understand the transport, coherence, and delocalization properties of BECs. Analyzing the interactions within and between regions of a BEC adds to the ultimate goal of building a quantum simulator.
