Atomic cousins team up in early quantum networking nodeResearchers use different ion species for storage and communication.
Large-scale quantum computers, which are an active pursuit of many university labs and tech giants, remain years away. But that hasn’t stopped some scientists from thinking ahead, to a time when quantum computers might be linked together in a network or a single quantum computer might be split up across many interconnected nodes.A group of physicists at the University of Maryland, working with...

What makes a university physics lab tick? Sean Kelley grabs a mic and heads to a lab that's trying to build an early quantum computer out of atomic ions. Marko Cetina and Kai Hudek, two research scientsts at the University of Maryland who run the lab, explain what it takes to keep things from burning down and muse about the future of quantum computers. This is the first installment of... Continue Reading
In Spring 2017, Jonathan Francisco San Miguel was awarded a National Science Foundation (NSF) Graduate Research Fellowship. This prestigious NSF fellowship recognizes outstanding students in science, technology, engineering and mathematics fields. Since 2014, he has been working on superconducting qubits in JQI Fellow Vladimir Manucharyan's condensed matter physics laboratory. Continue Reading
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...

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
Elizabeth Goldschmidt recently joined the quantum information science group at the Army Research Laboratory. She earned an undergraduate degree in physics at Harvard University. After, she went on to earn a PhD at JQI, where as part of Alan Migdall's research group, she worked on quantum memory and single photon technologies. She then received a National Research Council postdoctoral fellowship at NIST to work with Trey Porto on simulating condensed matter systems with ultracold atoms trapped in optical lattices. In her position at the Army Research Lab, she is starting a new experimental research program focused on quantum memory and quantum information in solid-state materials.
Stephen Powell, a former JQI postdoctoral fellow at CMTC, now works at the Nordic Institute of Theoretical Physics or Nordita in Stockholm, Sweden. His research in the group of Sankar Das Sarma centered around strongly correlated systems with a specific focus on frustrated magnetism and ultracold gases. At Nordita, he will continue this line of research, which is at the meeting point of condensed matter and atomic physics. In talking of his postdoctoral experience he says, “Something I've particularly enjoyed about being at JQI is having close contact with various experimental groups here.”
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.
Phil Richerme is a postdoc in Chris Monroe's Trapped Ion Quantum Information Group. He studies quantum magnetism using a well-controlled and well-isolated system of atomic ion spins, realizing Feynman's original proposal for a quantum simulator. These experiments probe the ground state and dynamical evolution of interacting spin systems, which are difficult (or impossible) for classical computers to calculate for even a few dozen spins. Phil received his Ph.D. from Harvard in 2012, working with Gerald Gabrielse and the ATRAP collaboration at CERN to trap antihydrogen atoms for sensitive tests of CPT symmetry.
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.
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.
