Lauren Aycock, a recent JQI graduate researcher, has been awarded a Congressional Science Fellowship from the American Physical Society.The fellowship, which lasts for one year, aims to provide members of Congress with the scientific and technical expertise of trained scientists. In turn, fellows like Aycock get to learn first-hand about public policy and communicate with Congress on behalf of... Continue Reading
Trapped ions and superconductors face off in quantum benchmark
The race to build larger and larger quantum computers is heating up, with several technologies competing for a role in future devices. Each potential platform has strengths and weaknesses, but little has been done to directly compare the performance of early prototypes. Now, researchers at the JQI have performed a first-of-its-kind benchmark test of two small quantum computers built from... Continue Reading

Physics professor and JQI Fellow Fred Wellstood has been appointed the newest UMD Co-Director of JQI. He assumed the role on March 1."Fred has played a major role in the JQI since its founding," says Gretchen Campbell, the current NIST Co-Director of JQI. "Most recently, his tireless efforts helped to design and ultimately build the new Physical Sciences Center at Maryland that many JQI labs... Continue Reading
Destabilized solitons perform a disappearing actIn the presence of impurities, dark solitons accelerate and vanish from sight
When your heart beats, blood courses through your veins in waves of pressure. These pressure waves manifest as your pulse, a regular rhythm unperturbed by the complex internal structure of the body. Scientists call such robust waves solitons, and in many ways they behave more like discrete particles than waves. Soliton theory may aid in the understanding of tsunamis, which—unlike other water...

Crossing the quantum-chaotic divideResearchers take a closer look at the emergence of quantum effects and the destruction of chaos.

Chaos is all around us, a fact that weather forecasters know all too well.Their job is notoriously difficult because small changes in air pressure or temperature, which ultimately drive winds and weather systems, can have huge consequences on a global scale. This sensitivity to tiny differences is commonly called the butterfly effect, and it makes weather patterns chaotic and hard to predict.... Continue Reading
Heads up, high school class of '19: New measurement unit definitions are comingThe meter and the second will soon be pegged to fundamental constants like the speed of light and the charge of the electron.

Next year, scientists expect to change the way we define the basic units with which we measure our universe. An article by scientists at the National Institute of Standards and Technology (NIST) written for teachers will help ensure high school physics students are hip to the news.The brief, six-page article, which appears in this month’s issue...

Aaron Lee, a JQI graduate student, received his undergraduate degree in physics at UMD. He worked with Chris Monroe’s trapped ion group, using ytterbium ions to simulate other quantum systems. As a graduate student, he has continued to study quantum information with the Monroe group and hopes his work can contribute to eventually building a quantum computer.
Campbell is a NIST JQI fellow and works in the Laser Cooling and Trapping group. In her atom circuits lab, reserachers probe Na BECs in toroidal traps. The goals of these experiments include studying superfluidity, as well as superfluid analogs to superconducting circuits. A second experiment with ultracold strontium is being built. She received a Ph.D from MIT in 2006, where she worked with Wolfgang Ketterle and Dave Pritchard. There, she used Rb BECs in optical lattices to study atom interferometry, nonlinear atom optics and the superfluid – Mott insulator phase transition. These experiments included the first direct observation of the atomic recoil momentum in dispersive media. More recently, she worked with Jun Ye on precision measurements and frequency metrology with an 87Sr optical lattice clock.
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.
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/
Zachary Eldredge, a PhD student at JQI and QuICS, received undergraduate degrees in physics and mathematics from the University of Oklahoma. At JQI, he has studied the emergence of a self-organized structure in atoms near a nanofiber, working closely with Luis Orozco’s to investigate nanofiber platforms and cold atom physics. Now, he works with Alexey Gorshkov and studies the physics of long-range quantum information and quantum networks.
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.
