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...

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...

Optical fibers are the backbone of modern communications, shuttling information from A to B through thin glass filaments as pulses of light. They are used extensively in telecommunications, allowing information to travel at near the speed of light virtually without loss.These days, biologists, physicists and other scientists regularly use optical fibers to pipe light around inside their labs....

If the looming holiday lull leaves you yearning for news from the quantum world, JQI has you covered. Below we present an overview of our major research and outreach activities from the past year, which marked JQI’s tenth anniversary.In 2016, JQI students, postdocs and Fellows published more than 120 academic papers, about half of which were enabled by the National Science Foundation's ...

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...

Former NRC postdoctoral fellow Steven Olmschenk is currently faculty at Denison University located in Granville, Ohio. Steve was a graduate student in Chris Monroe’s Trapped Ion Quantum Information group and then a postdoc in the NIST Laser Cooling and Trapping Group. While at NIST he worked on Trey Porto’s double-well optical lattice experiment. At Dension he has a group researching physics at the interface of quantum optics and trapped atomic ions http://personal.denison.edu/~olmschenks/.
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.
Dong-Ling Deng is a JQI Postdoctoral Fellow working in the Condensed Matter Theory Center at UMD. He received his PhD in physics from the University of Michigan, and his research interests include quantum information theory and topological phases of matter. He has proposed a new kind of random number generator based on Majorana fermions, which would be able to generate random numbers with unconditional security. Outside of working hours Deng loves to read classic Chinese novels and play badminton.
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.
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.”
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.”
