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. Located on the campus of the University of Maryland (UMD) at College Park, Maryland, Joint Quantum Institute was created on September 11, 2006 by a joint memorandum of understanding among University of Maryland, the National Institute of Standards and Technology (NIST) and the Laboratory for Physical Sciences. It has a base annual budget of approximately $6 million, which supports both theory and experimental research by Joint Quantum Institute’s 27 Fellows, associated graduate students and postdoctoral scientists. Joint Quantum Institute’s co-directors are Steve Rolston, Professor of Physics at University of Maryland, and Charles W. Clark, Adjunct Professor of Physics at University of Maryland. Approximately half the Joint Quantum Institute fellows are from University of Maryland and half from NIST. One is from the Laboratory for Physical Sciences, a university-government facility adjacent to the UMD College Park campus.
Lab sets a new record for creating heralded photons
(Phys.org) —Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable ...

16 atomic ions simulate a quantum antiferromagnet
(Phys.org) —Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter ...

Quantum dot commands light: A solid state ultrafast logic gate on a photon
(Phys.org) —If you could peek at the inner workings of a computer processor you would see billions of transistors switching back and forth between two states. In optical communications, information from ...

Using single quantum dots to probe nanowires
Modern telecommunications happens because of fast electrons and fast photons. Can it get better? Can Moore's law—the doubling of computing power ever 18 months or so—be sustained? Can the compactness ...

Freezing magnetic monopoles: How dipoles become monopoles and vice versa
Magnetic monopoles, entities with isolated north or south magnetic poles, weren't supposed to exist. If you try to saw a bar magnet in half, all you succeed in getting are two magnets, each with a south and ...
