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....

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
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.
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.
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.
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.
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/
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.
