Interacting Ion QutritsEnlisting symmetry to protect quantum states from disruptions
In quantum mechanics, symmetry describes more than just the patterns that matter takes — it is used to classify the nature of quantum states. These states can be entangled, exhibiting peculiar connections that cannot be explained without the use of quantum physics. For some entangled states, the symmetry of these connections can offer a kind of protection against disruptions. Physicists are... Continue Reading
JQI Fellow and NIST Scientist Gretchen Campbell has recently been announced as the IUPAP 2015 Young Scientist Prize recipient in the field of Atomic, Molecular, and Optical Physics. The organization cited her "outstanding contributions in toroidal Bose-Einstein condensates and its application to "atomtronic" circuits."
The International... Continue Reading
Qubit ChemistryControlling interactions between distant qubits
A big part of the burgeoning science of quantum computation is reliably storing and processing information in the form of quantum bits, or qubits. One of the obstacles to this goal is the difficulty of preserving the fragile quantum condition of qubits against unwanted outside influence even as the qubits interact among themselves in a programmatic way.
Spin qubits are one of the most... Continue Reading
Collecting Lost LightRayleigh scattering reveals light propagation in optical nanfibers
Optical fibers are hair-like threads of glass used to guide light. Fibers of exceptional purity have proved an excellent way of sending information over long distances and are the foundation of modern telecommunication systems. JQI researchers in collaboration with scientists from the Naval Research Laboratory have developed a new technique for visualizing light propagation through an optical... Continue Reading

In the quest to better explain and even harness the strange and amazing behaviors of interacting quantum systems, well-characterized and controllable atomic gases have emerged as a tool for emulating the behavior of solids. This is because physicists can use lasers to force atoms in dilute quantum gases to act, in many ways, like electrons in solids. The hope is studying the same physics in... Continue Reading

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.
David Hucul is a graduate student in Professor Chris Monroe's trapped ion quantum information lab at the Joint Quantum Institute. He earned undergraduate degrees in physics and chemistry in 2006 from the University of Michigan and a master's degree at MIT in 2009 under Wolfgang Ketterle. David started his PhD work with Chris Monroe in 2009 working on using frequency combs to entangle trapped ions. He now works on entangling trapped atoms within and between ion traps using both phonons and photons to create quantum networks.
David became interested in atomic physics by accident, when he enjoyed an advanced chemistry course about spectroscopy and realized it was really physics. His first physics seminar was given by Chris Monroe, who was then a professor at Michigan. This made him a physicist.
He expects to finish his graduate studies sometime in 2015 and hopes to find a postdoctoral position after that.
Alexey V. Gorshkov
Alexey Gorshkov is a JQI fellow and theoretical physicist at NIST. He grew up in Moscow until his parents brought him to Boston when he was in 10th grade. In high school, he was good at math, so that's what he was planning to do in college, but then math ended up being too dry. Physics offered a perfect alternative since it involved lots of interesting mathematics and grappled with problems related to real life.
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.”
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/
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.
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/.
