Physicists produce quantum-entangled images from PhysOrg.com
Using a convenient and flexible method for creating twin light beams, researchers at the Joint Quantum Institute of the Commerce Department's National Institute of Standards and Technology and the University of Maryland have produced "quantum images," pairs of information-rich visual patterns whose features are "entangled," or inextricably linked by the laws of quantum physics. In addition to promising better detection of faint objects and improved amplification and positioning of light beams, the researchers' technique for producing quantum images—unprecedented in its simplicity, versatility, and efficiency—may someday be useful for storing patterns of data in quantum computers and transmitting large amounts of highly secure encrypted information. The research team, led by JQI's Paul Lett, describes the work in the June 12 edition of Science Express.

'N-variant' microchips could protect intellectual property, enable new services from PhysOrg.com
Rice University computer engineers have created a way to design integrated circuits that can contain many multiple selves. The chips can assume one identify or a subset of identities at a time, depending on the user's needs. New research shows that multiple "personalities" in an integrated circuit can be even a more powerful security mechanism that can be used for a variety of digital rights management tasks as well as for circuit optimization and customization without sacrificing the related power, delay and area metrics.

'Nanoglassblowing' Seen as Boon to Study of Individual Molecules from PhysOrg.com
While the results may not rival the artistry of glassblowers in Europe and Latin America, researchers at the National Institute of Standards and Technology and Cornell University have found beauty in a new fabrication technique called “nanoglassblowing” that creates nanoscale (billionth of a meter) fluidic devices used to isolate and study single molecules in solution—including individual DNA strands. The novel method is described in a paper posted online this week in the journal Nanotechnology.

Scientists show quantum systems could flout physics law from PhysOrg.com
Scientists in the Weizmann Institute's Faculty of Chemistry, together with colleagues in Germany, have made a startling prediction: Simply 'taking the temperature' of certain quantum systems at frequent intervals might cause them to disobey a hard and fast rule of thermodynamics.

A computer that can 'read' your mind from PhysOrg.com
For centuries, the concept of mind readers was strictly the domain of folklore and science fiction. But according to new research published today in the journal Science, scientists are closer to knowing how specific thoughts activate our brains. The findings demonstrate the power of computational modeling to improve our understanding of how the brain processes information and thoughts.
