| Physicists demonstrate quantum integrated circuit that implements quantum von Neumann architecture Posted: 01 Sep 2011 12:52 PM PDT A new paradigm in quantum information processing has been demonstrated. Physicists have developed a quantum integrated circuit that implements the quantum von Neumann architecture. In this architecture, a long-lived quantum random access memory can be programmed using a quantum central processing unit, all constructed on a single chip, providing the key components for a quantum version of a classical computer.  |
| Physicists capture microscopic origins of thinning and thickening fluids Posted: 01 Sep 2011 11:21 AM PDT In things thick and thin: Physicists now explain how fluids -- such as paint or paste -- behave by observing how micron-sized suspended particles dance in real time. Using high-speed microscopy, the scientists unveil how these particles are responding to fluid flows from shear -- a specific way of stirring.  |
| Posted: 01 Sep 2011 11:21 AM PDT Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led to a reformulation of the mathematical laws that predict the path of a ray of light bouncing off a surface or traveling from one medium into another -- for example, from air into glass.  |
| Understanding next-generation electronic devices: Smallest atomic displacements ever Posted: 01 Sep 2011 11:20 AM PDT Scientists have developed a novel X-ray technique for imaging atomic displacements in materials with unprecedented accuracy. They have applied their technique to determine how a recently discovered class of exotic materials -- multiferroics -- can be simultaneously both magnetically and electrically ordered. Multiferroics are also candidate materials for new classes of electronic devices. The discovery is a major breakthrough in understanding multiferroics.  |
| Biological 'computer' destroys cancer cells: Diagnostic network incorporated into human cells Posted: 01 Sep 2011 11:20 AM PDT Researchers have successfully incorporated a diagnostic biological "computer" network into human cells. This network recognizes certain cancer cells using logic combinations of five cancer-specific molecular factors, triggering cancer cells destruction.  |
| NASA's Chandra finds nearest pair of supermassive black holes Posted: 01 Sep 2011 11:12 AM PDT Astronomers using NASA's Chandra X-ray Observatory discovered the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way. Approximately 160 million light years from Earth, the pair is the nearest known such phenomenon.  |
| Digital quantum simulator developed Posted: 01 Sep 2011 11:03 AM PDT Physicists in Austria have come considerably closer to their goal to investigate complex phenomena in a model system: They have developed a digital, and therefore, universal quantum simulator in their laboratory, which can, in principle, simulate any physical system efficiently.  |
| Posted: 01 Sep 2011 07:54 AM PDT Using Hubble Space Telescope images, astronomers have created time-lapse movies that offer astronomers their first glimpse of the dynamic behavior of stellar jets, huge torrents of gas and particles that spew from the poles of newborn stars. The movies are forcing astronomers to rethink the late stages of star birth. The researchers are also using lasers to recreate small-scale versions of the jets.  |
