Researchers have built a quantum logic gate in an optical fiber, laying the foundation for a quantum computer network.

The promise of quantum computers is tantalizingly great: near-instantaneous problem solving, and perfectly secure data transmission. For the most part, however, small-scale demonstrations of quantum computation remain isolated in labs throughout the world.
Now, Prem Kumar, a professor of electrical engineering and computer science at Northwestern University, has taken a step toward making quantum computing more practical. Kumar and his team have shown that they can build a quantum logic gate--a fundamental component of a quantum computer--within an optical fiber. The gate could be part of a circuit that relays information securely, over hundreds of kilometers of fiber, from one quantum computer to another.
It could also be used on its own to find solutions to complicated mathematical problems.

MaxStream has introduced a long range wireless bridge that expands the capabilities of high-speed Ethernet networks.
The XPress Ethernet Bridge allows host and client Ethernet connections to communicate at a range of up to 15 miles (line-of-sight with high gain antennas) at speeds up to 1.5 Mbps.

The XPress Ethernet Bridge optimizes long-range, high-speed data transmission when the cost of laying CAT5 cable is impractical and 802.11 (Wi-Fi™) fails to meet range requirements or is over-saturated.

Delaware-based communications company Nethercomm Corporation has announced a new broadband technology promising massive bandwidth with minimal additional infrastructure investmentment required.

Nethercomm’s Broadband-in-Gas (BiG) carries enormous amounts of data through existing subterranean gas pipes instead of over the air (with constraints and interference), to offer much greater bandwidth and hence access to content and services beyond that which has been available to date.

BiG (note that acronym – you’ll certainly hear more of it) uses Ultra Wideband technology to wirelessly broadcast information in a way that is both safe and reliable by using the private spectrum isolated within natural gas pipelines.

Hong Kong Broadband Network (HKBN) officially launched its 1 Gbps symmetric service for the residential market.

Approximately 800,000 households, out of a total of 2.2 million households in Hong Kong, are wired to receive the service.
The 1 Gbps symmetric service is priced at US$215 per month.

What is I2P?

I2P is an anonymous network, exposing a simple layer that applications can use to anonymously and securely send messages to each other. The network itself is strictly message based (ala IP), but there is a library available to allow reliable streaming communication on top of it (ala TCP).

All communication is end to end encrypted (in total there are four layers of encryption used when sending a message), and even the end points ("destinations") are cryptographic identifiers (essentially a pair of public keys).

Chip delays have apparently pushed out the mass deployment of ADSL2+ broadband technology until 2005 — a year later than originally expected by carriers, according to an e-mail newsletter from DSL Prime.

ADSL2+ is the standard consented by the ITU in January 2003. It is based on ADSL2 and doubles the maximum frequency used for downstream data transmission from 1.1- to 2.2-MHz. The technology is capable of data rates up to 25-megabits-per-second, doubling the downstream bandwidth of ADSL.

Several chip makers and DSLAM vendors have rolled out products based on ADSL2+ and promised mass deployments in 2004. But in a newsletter issued this week, DSL Prime claims that ADSL2+ is "still a year away."

Internet Advertising Revenues Nearly Total $2.3 Billion

Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers (PwC) announced that Internet advertising totaled nearly $2.3 billion in the first quarter of 2004 - the highest quarterly total on record since PwC and IAB began tracking revenues in 1996.

This quarter also marks a 38.9% increase over Q1 2003 ($1.6 billion) and a 3.9% increase over Q4 2003 ($2.2 billion.)

The IAB sponsors the Internet Ad Revenue Report, which is conducted independently by PwC.

The Web Services Choreography Description Language (WS-CDL) is an XML-based language that describes peer-to-peer collaborations of Web Services participants by defining, from a global viewpoint, their common and complementary observable behavior; where ordered message exchanges result in accomplishing a common business goal.

The Web Services specifications offer a communication bridge between the heterogeneous computational environments used to develop and host applications.

The future of E-Business applications requires the ability to perform long-lived, peer-to-peer collaborations between the participating services, within or across the trusted domains of an organization.

Building on the success of satellite transmission specification DVB-S, DVB-S2 offers greater flexibility and better performance over existing satellites at reasonable cost.

The new open specification offers a 30 percent capacity increase under the same transmission conditions, more robust reception for the same spectrum efficiency and will operate from Carrier-to-Noise ratios as low as - 2 dB to + 16 dB. Spectrum efficiencies up to 4.5 bit/sec/Hz can be achieved.

Caltech and CERN send data at more than 6.25 Gbps across nearly 11,000 km

An international team has set a new Internet2(R) Land Speed Record by transferring data across nearly 11,000 kilometers at an average rate of 6.25 gigabits per second (Gbps), nearly 10,000 times faster than a typical home broadband connection, from Los Angeles, Calif. to Geneva, Switzerland.

The Internet2 Land Speed Record (I2-LSR) is an open and ongoing competition for the highest-bandwidth, end-to-end networks.
