Deep within solids, individual electrons zip around on a nanoscale highway paved with atoms. For the most part, these electrons avoid one another, kept in separate lanes by their mutual repulsion. But vibrations in the atomic road can blur their lanes and sometimes allow the tiny particles to pair up. The result is smooth and lossless travel, and it’s one way to create superconductivity.But...

Quantum Thermometer or Optical Refrigerator?Versatile optomechanical beams have potential applications in biology, chemistry, electronics.
- June 23, 2017
- Research News
In an arranged marriage of optics and mechanics, JQI-NIST physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. Able to operate in ordinary, room-temperature environments, yet exploiting some of the deepest principles of quantum physics, these optomechanical systems can act as inherently accurate thermometers, or conversely, as a...

Researchers have found that a small stretch is enough to unleash the exotic electrical properties of a recently discovered topological insulator, unshackling a behavior previously locked away at cryogenic temperatures.The compound, called samarium hexaboride, has been studied for decades. But recently it has enjoyed a surge of renewed interest as scientists ... Continue Reading
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

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.
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.
Mary Lyon is originally from Princeton, New Jersey. She attended Bryn Mawr College, where she earned both her undergraduate degree in physics and a high school teaching certificate. Lyon originally planned to be a high school physics teacher, but discovered a love for research during a summer program at MIT the summer after her junior year. She briefly taught high school in Columbus, GA before going to graduate school at Brigham Young University, where she worked with Scott Bergeson on strongly coupled ultracold neutral plasmas. She is currently a JQI postdoctoral researcher in the group of Trey Porto and Steve Rolston where she is building a new quantum information experiment that will use an ensemble of cold Rydberg atoms.
Ryan Barnett, a former JQI postdoctoral fellow at the Condensed Matter Theory Center (CMTC), is now a ‘Lecturer in Condensed Matter Theory’ (UK equivalent of assistant professor) at Imperial College in London. Ryan is a theoretical physicist interested in collective effects in ultracold atomic gases. While at the JQI his research focused on spinor condensates, non-equilibrium dynamics, and synthetic gauge fields. Much of his recent work at CMTC was motivated by ongoing experimental activities at the JQI.
Michael Foss-Feig is a JQI postdoctoral scientist. As an undergraduate at Amherst College, Michael performed some experimental work in solid-state physics with professor Jonathan Friedman. He, then, went to University of Colorado where he received a physics PhD in October 2012. His thesis, prepared under the supervision of Ana Maria Rey, was entitled “Quantum simulation of many-body physics with neutral atoms, molecules and ions.” This work earned him the DAMOP Thesis Prize in June 2013. Now a NRC postdoctoral fellow at NIST working under Charles Clark, Michael’s interests are centered around many-body physics with ultracold atomic, molecular, and optical systems. He also studies long-range interacting systems, such as trapped ions, ultracold dipolar molecules, and Rydberg atoms.
James R. Williams
James R. Williams is a JQI Fellow and assistant professor of physics, and his chief area of research is experimental condensed matter physics. Specifically, he specializes in understanding why certain one and two-dimensional materials (e.g. topological insulators, graphene) depart from normal conductivity provided by free electrons. Dr. Williams received his bachelors in engineering physics at Santa Clara University. He then went on to get his MS and PhD from Harvard University in 2009 on the subject of grapheme, while studying under Charles M. Marcus. He was then a postdoctoral fellow at Stanford before coming to Maryland.
