People Profiles

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.
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.
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.
Dong-Ling Deng

Dong-Ling Deng is a JQI Postdoctoral Fellow working in the Condensed Matter Theory Center at UMD. He received his PhD in physics from the University of Michigan, and his research interests include quantum information theory and topological phases of matter. He has proposed a new kind of random number generator based on Majorana fermions, which would be able to generate random numbers with unconditional security. Outside of working hours Deng loves to read classic Chinese novels and play badminton.
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.
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.
