Atomic beltway could solve problems of cosmic gravity
When is a traffic jam not a traffic jam? When it's a quantum traffic jam, of course. Only in quantum physics can traffic be standing still and moving at the same time. A new theoretical paper from scientists at the National Institute of Standards and Technology (NIST) and the University of Maryland suggests that intentionally creating just such a traffic jam out of a ring of several thousand...

Artificial atoms shed light on the future of security
From credit card numbers to bank account information, we transmit sensitive digital information over the internet every day. Since the 1990s, though, researchers have known that quantum computers threaten to disrupt the security of these transactions. That’s because quantum physics predicts that these computers could do some calculations far faster than their conventional counterparts. This... Continue Reading
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...

Physics Nobel honors underpinnings of exotic matter
A trio of researchers who laid the foundation for understanding numerous exotic phases of matter have split the 2016 Nobel Prize in Physics.The Royal Swedish Academy of Sciences awarded the prize "for theoretical discoveries of topological phase transitions and topological phases of matter" to three laureates: David Thouless of the University of Washington, Duncan Haldane of Princeton...

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
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.
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.
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 Maghrebi earned his PhD in physics at the Massachusetts Institute of Technology, where he received the Sergio Vazquez Prize for his research on quantum fluctuations. For his postdoctoral research at JQI, he is working towards understanding non-equilibrium phases of matter in hopes of creating states of matter that do not occur outside the lab. He is also working on quantifying entanglement of many-body systems in equilibrium as well as finding patterns of entanglement generation outside of equilibrium.
Stephen Eckel is postdoctoral researcher at the JQI, and a National Research Council postdoctoral fellow from 2013-2014. After receiving his undergraduate degree in physics at Lehigh University, he received numerous fellowships and prizes while pursuing a PhD in physics at Yale. There, he performed two precision measurements searching for the electron’s electric dipole moment, one using a solid-state sample and another using molecular lead-oxide. At JQI, he works with Gretchen Campbell on creating superfluid analogs of superconducting quantum interference devices (SQuIDs) using Bose-Einstein condensates of sodium atoms. He is currently working with a team of graduate students to build a new experiment that can incorporate both ultra-cold sodium and erbium.
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.
