(A mysterious entity called dark energy, accounts for the other 68%.) Welcome to the official facebook page of the Joint Quantum Institute! The Joint Quantum Institute (JQI) is pursuing that goal through the work of leading quantum scientists from the Department of Physics of the University of Maryland (UMD), the National Institute of Standards and Technology (NIST) and the Laboratory for Physical Sciences (LPS). Continue Reading, A paper coauthored by JQI Fellow Ian Spielman in 2011 has been highlighted by the journal Physical Review A as part of its 50th anniversary celebration—one of only 26 that the journal plans to highlight in its “anniversary milestones” collection.The collection comprises papers published in the journal “that have made important contributions to atomic, molecular, and optical physics... Continue Reading, JQI Fellow Christopher Monroe has been elected as a Fellow of The Optical Society (OSA). Created in 2006 to pursue theoretical and experimental studies of quantum physics in the context of information science and technology, JQI is located on UMD's College Park campus. 467 were here. There, he worked on precision measurement experiments that searched for the electric dipole moment of electrons bound to thorium oxide molecules. The Joint Quantum Institute (JQI) is a publicly funded research organization dedicated to basic and applied research in quantum physics, with particular emphasis on quantum information science. Helpful links to external quantum research and related departments at the University of Maryland College Park. In the early evening of Sunday, Oct. 7, 1900—120 years ago today—Max Planck found the functional form of the curve that we now know as the Planck distribution of black-body radiation. The agency already operates a Joint Quantum Institute and a Joint Center for Quantum Information and Computer Science with the University of Maryland. The joint quantum entropy generalizes the classical joint entropy to the context of quantum information theory.Intuitively, given two quantum states and , represented as density operators that are subparts of a quantum system, the joint quantum entropy is a measure of the total uncertainty or entropy of the joint system. And in curved space, normal ideas of geometry and straight lines break down, creating a chance to explore an unfamiliar landscape governed by new rules. Even a two-dimensional, physical version of a hyperbolic space is impossible to... Continue Reading, JQI Fellow Alicia Kollár has been awarded a grant by the Air Force’s Young Investigator Research Program (YIP). 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. The Joint Quantum Institute (JQI) is pursuing that goal through the work of leading quantum scientists from the Department of Physics of the University of Maryland (UMD), the National Institute of Standards and Technology (NIST) and the Laboratory for Physical Sciences (LPS). While in the group she focused on ultrafast spin manipulation as well as quantum simulation of magnetism. Continue Reading, Thanks to Einstein, we know that our three-dimensional space is warped and curved. JILA is located on the University of Colorado Boulder campus. Dark matter makes up about 27% of the universe; ordinary matter, such as the stuff that builds stars and planets, accounts for just 5% of the cosmos. 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. One type of non-Euclidean geometry that is of interest is hyperbolic space. There, he helped design silicon chips with embedded quantum logic. Crystal Senko was a graduate student in Chris Monroe's ion trapping group. The two researchers are Sankar Das Sarma, the Director of the Condensed Matter... Continue Reading, To mark the 50th anniversary of Physical Review B, editors selected “milestone” papers that have made lasting contributions to condensed matter physics, including one co-written by JQI Fellow Sankar Das Sarma. The two researchers are Sankar Das Sarma, the Director of the Condensed Matter Theory Center and the Richard E. Prange Chair and Distinguished University Professor of Physics at the University of Marlyand (UMD), and Christopher Monroe, Distinguished University Professor and the Bice Zorn Professor of Physics at UMD and a Fellow of the Joint Center for Quantum Information and Computer Science. 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.
