Analog box in disguise? Few start-ups would have the guts or audacity to unveil their first product at the Computer History Museum. D-Wave Systems, however, did just that today by unveiling the world's most advanced quantum computer - a product that may one day be displayed at the museum as a breakthrough system or simply as a curious relic.â¦

(InfoWorld) - Researchers from Intel and the University of California at Santa Barbara have found a way to build low-cost "laser chips" that could eventually shuttle data around PCs at much higher speeds than today's copper wire interconnects. The researchers combined the properties of a compound semiconductor material called indium phosphide, which emits light constantly, and silicon, which can be used to amplify and direct that light. They sandwiched the materials together to create a single device that can be manufactured using standard chip-making techniques. The breakthrough, announced Monday, is significant because it could help the interconnect technologies that carry data between components in PCs and servers to keep pace with the rapid advances in processing power of the chips themselves, the researchers said. "This could bring low-cost, terabit-level optical 'data pipes' inside future computers and help make possible a new era of high-performance computing applications," said Mario Paniccia, director of Intel's Photonics Technology Lab, in a statement. The work may be several years away from commercialization, but the researchers expect eventually to be able to put dozens or even hundreds of lasers on a single chip, they said. Indium phosphide is already widely used to make lasers for fiber optic networks, but the cost of assembling and aligning the lasers makes them too expensive for the high-volume PC business. Silicon, on the other hand, can amplify and control light and could be used more affordably, but it is not an efficient generator of light itself. The researchers figured out a way to combine the two materials to build a "hybrid silicon laser" that can be manufactured using Intel's standard manufacturing techniques, keeping costs relatively low. To make the silicon laser they created a thin oxide layer roughly 25 atoms thick on the surface of each material. They then heated the oxide and pressed the two layers together, forming a single chip with a "glass glue" between them. Applying a voltage to the device generates light from the indium phosphide, which passes through the joining layer to be guided and controlled by the silicon. The laser light can send data between computer components at extremely high speed. This can be done using a "silicon optical modulator," which effectively turns the laser beam on and off at very high speeds to represent the 1s and 0s of computer code. Intel has already demonstrated a silicon modulator that can transmit data at up to 10Gb per second. Figuring out how to make the hybrid silicon laser was the last big barrier to using silicon-based optical devices in computers and data centers, the researchers said.

(InfoWorld) - Quantum introduced a disk storage appliance Monday that could both appeal to enterprise customers and improve its partnerships with other storage vendors. Quantum's DXi7500 is an integrated data deduplication, disk backup, and tape archiving device, also called a VTL (virtual tape library), that is a complement to the smaller DXi3500 and DXi5500 modelsÂ Quantum introduced in December 2006. The DXi7500 offers up to 240TB of disk storage capacity, versus 4.2TB and 11TB for the 3500 and 5500, respectively. A terabyte is 1,000 gigabytes of data. The new model also has a healthy appetite for data, deduplicating and saving it to disk at the rate of 8TB per hour. The DXi7500 would serve an enterprise by taking data already deduplicated by the smaller DX appliances at remote offices of a company and deduplicating it further, said Mike Sparkes, product manager for disk systems at Quantum. Deduplication is the software-based process of searching through data and eliminating multiple copies of files so that less data needs to be saved to disk storage. The Quantum system also creates a backup tape copy of that data, which is stored for archiving purposes. The system eliminates the need for tape backup at remote locations, which can be difficult for limited staffs there to manage. "Suddenly, you get to retain two or three months of backup data instead of two or three days," said Sparkes. "Instead of just being a buffer to tape, which VTLs have usually been, it becomes more of a permanent repository of backup data." The DXi7500 also gives enterprise storage managers the option of using either the in-line or post-process approach to saving to disk. With the in-line approach, data is transferred from a production server to the disk storage appliance for deduplication, but that is a time-consuming process that ties up the server, preventing it from doing more computing. The post-process approach moves data off the server quickly so the server can get back to work, but requires additional capacity in the storage appliance to hold all that data while it deduplicates it. Giving storage administrators a choice is welcome, said Robert Amatruda, research manager at IDC. "What they are doing is to provide some flexibility for the customers." VTLÂ technology is a nascent market, Amatruda said. IDC forecasts market revenue to grow to $4.1 billion by 2011 and for the amount of data stored in VTL systems to increase at a compound annual growth rate of 47.4 percent over the same period. Quantum can leverage the DXi7500 to strengthen existing ties with OEMs, such as Hewlett-Packard, Sun, and others, said Greg Schulz, founder of Storage I/O Group, an industry research and consulting firm. "Quantum sells a turnkey solution, which means for an OEM that they can just put their logo on it andÂ rebadge it, and people will buy it knowing it's a Quantum-based product," said Schulz.

This is a series of four articles each with a separate explanation of different phenomena. Each of the four articles is a piece of a mosaic and so every one is needed to understand the final explanation of the quantum astronomy experiment we will be proposing to do possibly using the Allen Array Telescope and the narrow-band radio-wave detectors being build by the SETI Institute and the University of California, Berkeley.
