The Quantum Wire

First universal programmable quantum computer unveiled
New Scientist -- The world's first universal programmable quantum computer has been put through its paces. But the test program revealed significant hurdles that must be overcome before the device is ready for real work.
Condensed-matter physics: Dirac electrons broken to pieces
Nature -- News & Views: Graphene continues to surprise physicists with its remarkable electronic properties. Experiments (here and here) now show that electrons in the material can team up to behave as if they are only fragments of themselves. [PDF]
Sr.Just right for forming a Bose-Einstein condensate
Physics -- Viewpoint: Two separate teams have achieved the long sought after Bose-Einstein condensation of strontium.
Quantum gas microscope offers glimpse of quirky ultracold atoms
EurekAlert -- Physicists have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in bizarre ways.
Creating a six-qubit cluster state
PhysOrg -- A team of researchers believes their new results represent the first time a six-qubit linear cluster state, built using a two-photon triple entangled state, has been experimentally demonstrated.
Caught at the finishing line
Nature -- News & Views: Quantum systems habitually leak information, limiting their usefulness for practical applications. By optimally reversing the leak, this information loss has been reduced to a trickle in the solid state. [PDF]
Quantum computers could tackle enormous linear equations
Science News -- A new algorithm may give quantum computers a new, practical job: quickly solving monster linear equations. Such problems are at the heart of complex processes such as image and video processing, genetic analyses and even Internet traffic control.
Weird "Particles" Spotted in Hot New Material
ScienceNOW -- A team of physicists has taken a key step in fulfilling graphene’s promise as a hotbed of exotic physics by showing that the electrons within it can team up to behave like particles with a fraction of the electron's charge.

About

The Joint Quantum Institute is a research partnership between University of Maryland (UMD) and the National Institute of Standards and Technology, with the support and participation of the Laboratory for Physical Sciences.

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.
