Move over, lasers: Scientists can now create holograms using neutrons
- October 20, 2016
- Research News
For the first time, a team including scientists from the National Institute of Standards and Technology (NIST) and JQI have used neutron beams to create holograms of large solid objects, revealing their interior details in ways that ordinary holograms do not.Holograms—flat images that look like three-dimensional objects—owe their striking look to interfering waves. Both matter and light behave... Continue Reading
L'Oréal-UNESCO award goes to former JQI student researcher
Karina Jiménez-García, a former visiting graduate student who worked with JQI Fellow Ian Spielman, was one of 30 young women scientists to receive a 2016 L'Oréal-UNESCO For Women in Science fellowship. She was selected from a pool of more than 1,000 applicants and received the award for her ongoing research on the quantum behavior of... Continue Reading
For decades, particle accelerators have grabbed headlines while smashing matter together at faster and faster speeds. But in recent years, alongside the progress in high-energy experiments, another realm of physics has been taking its own exciting strides forward.That realm, which researchers call condensed matter physics, studies chunks of matter moving decidedly slower than the protons in...

The JQI community joins our colleagues at JILA and NIST in mourning the loss of Deborah Jin, a pioneer in the physics of ultracold gases, an area of research that joins condensed matter and atomic physics. Jin was an outstanding scientist, colleague, and mentor. To learn more about Jin's life, research and accomplishments, please read the remembrances by ... Continue Reading
This Fall, theoretical condensed matter physicist Maissam Barkeshli joined the UMD Department of Physics as an Assistant Professor and a JQI Fellow. In 2010 he received a PhD from MIT under the supervision of Xiao-Gang Wen. Since then he has been a Simons Postdoctoral Fellow at Stanford University (2010-2013) and a postdoctoral researcher at Microsoft's Station Q, located at UC Santa Barbara (... Continue Reading

Programmable ions set the stage for general-purpose quantum computersA new quantum computer module combines proven techniques with advances in hardware and software.
Quantum computers promise speedy solutions to some difficult problems, but building large-scale, general-purpose quantum devices is a problem fraught with technical challenges.To date, many research groups have created small but functional quantum computers. By combining a handful of atoms, electrons or superconducting junctions, researchers now regularly demonstrate quantum effects and run... Continue Reading
Paul Hess is a postdoctoral fellow at JQI. He received his undergraduate degree in astrophysics at Williams College and went on to get his PhD in physics at Harvard University. There, he worked on precision measurement experiments that searched for the electric dipole moment of electrons bound to thorium oxide molecules. At JQI, as part of Chris Monroe’s trapped ion team, his work revolves around examining complex many body systems. He has studied many-body localization and is currently working on an experiment that would simulate quantum solids with an increased number of trapped ions.
Alexey V. Gorshkov
Alexey Gorshkov is a JQI fellow and theoretical physicist at NIST. He attended Harvard for his undergraduate and graduate degrees, obtaining a physics PhD in 2010 studying under Mikhail Lukin. After that he was a postdoctoral fellow at Caltech, working with John Preskill. He won numerous university teaching and research awards during these years. His research is at the intersection of AMO physics, condensed matter physics, and quantum information science. He has authored dozens of papers and has a patent entitled: “Scalable Room Temperature Quantum Information Processor.”
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.
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 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 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.
