New state of matter quantum spin Hall state could make better computers

three Stanford researchers proposed that a new state, called the quantum spin Hall effect, could be realized without applying an external magnetic field. Since quantum wells in mercury telluride/cadmium telluride sheets can be readily fabricated, it is possible to experimentally test the theoretical predictions of Zhang, Bernevig and Hughes. A research group at the University …

Samsung’s Plan for Terabit Flash Memory

Researchers at Samsung, one of the leading producers of flash-memory chips, recently announced a new chip that can hold twice as much data as before, and without an increase in its footprint on a circuit board. They were able to double the data capacity by building chips with multiple layers of silicon, creating 3-D structures. …

Quantum dot quantum computer progress

In Physical Review Letters, Oxford student Avinash Kolli and his coauthors suggest a new way to create entanglement, by identifying two different stable states of a quantum dot (call them ‘A’ and ‘B’) and then targeting two such dots simultaneously with a laser. A lot of work still needs to be done to flesh out …

2007 superconducting related technology predictions

‘Top-10’ forecast list released today by Elie K. Track, Ph.D., senior partner, HYPRES Inc., a leading developer of superconducting microelectronics technology. 1. Lab demonstrations that can lead to an advanced, low-cost MRI machine that leverages superconducting technology. Ultimately, this will make it easier and cheaper to screen for many serious medical conditions, such as breast …

Engineered Microbes Boost Ethanol

The yeast strain they made can tolerate ethanol concentrations as high as 18 percent–almost double the concentration that regular yeast can handle without quickly dying. In addition, the new strain makes about 20 percent more ethanol by processing more of the glucose, and it speeds up fermentation by 70 percent. So far the researchers have …

Plasmons – bridging optics and electronics

New light physics with plasmons that could bridge light, matter and electronics. Plasmon computers could operate at 100 Terahertz – 1000 terahertz or 20,000 to 200,000 times faster than mainstream computer chips. Part of what I think is the growing trend of greater control of all information, light, energy, matter and magnetism. (ILEMM) Two-dimensional light, …

2030 Energy forecast is 50% more coal usage

Coal is projected to increase 50% in the AEO2007 reference case, particularly for electricity generation. Coal consumption is projected to increase from 22.9 quadrillion Btu (1,128 million short tons) in 2005 to more than 34 quadrillion Btu (1,772 million short tons) in 2030, with significant additions of new coal-fired generation capacity over the last decade …
