Theoretical physicists studying the behavior of ultra-cold atoms have discovered a new source of friction, dispensing with a century-old paradox in the process. Their prediction, which experimenters may soon try to verify, was reported recently in Physical Review Letters.The friction afflicts certain arrangements of atoms in a Bose-Einstein Condensate (BEC), a quantum state of matter in which...

The idea of a pump is at least as old as the ancient Greek philosopher and scientist Archimedes. More than 2000 years ago, Archimedes allegedly invented a corkscrew pump that could lift water up an incline with the turn of a handle. Versions of the ancient invention still bear his name and are used today in agriculture and... Continue Reading

Quantum computers hold great potential, but they remain hard to build because their basic components—individual quantum systems like atoms, electrons or photons—are fragile. A relentless and noisy background constantly bombards the computer’s data. One promising theoretical approach, known as topological quantum computing, uses groups of special particles confined to a plane to combat this... Continue Reading

JQI Fellow Gretchen Campbell has been named the new NIST Co-Director of the Joint Quantum Institute, effective April 1, 2016. Campbell joined the JQI in 2009 and is also a UMD Adjunct Associate Professor and APS Fellow. In recent years she has received various accolades for her atomtronics research, including the APS Maria Goeppert-Mayer award. Campbell succeeds JQI Fellow Charles Clark, who... Continue Reading
Crystal Senko was a graduate student in Chris Monroe's ion trapping group. While in the group she focused on ultrafast spin manipulation as well as quantum simulation of magnetism. She is now a postdoctoral researcher with Mikhail Lukin at Harvard. Senko is an undergraduate alumni of Duke University, where she worked with Dan Gauthier on magneto-optical trapping using distributed feedback lasers.
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.
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.
Aftaab Dewan, a graduate fellow at JQI, received undergraduate degrees in physics and mathematics at Amherst College. There, he was a recipient of the Bassett Prize and the Stifler Prize, and conducted research on studying dynamics of Bose-Einstein Condensates. His senior thesis examined how neutrinos scatter off of materials such as lead or glass. He now works with Steve Rolston to understand the transport, coherence, and delocalization properties of BECs. Analyzing the interactions within and between regions of a BEC adds to the ultimate goal of building a quantum simulator.
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. He expects to finish his graduate studies sometime in 2015 and hopes to find a postdoctoral position after that.
Jonathan Vannucci, a graduate fellow at JQI, received undergraduate degrees in physics and mathematics at the University of Pittsburgh. There, his research focused on using nitrogen-vacancy centers in diamond as magnetic sensors. Now, he works in the quantum materials device laboratory with James Williams to engineer Silicon based nano-devices intended to probe the dynamics of the spin-glass transition near the Metal-Insulator-Transition in Silicon. They further wish to exploit this exotic many-body system in hope of developing new techniques of quantum computation.
