The document discusses three separate information technology related news articles. The first article discusses how ipNX in Nigeria plans to use WiMAX technology to offer both voice and broadband services, competing with mobile companies entering the internet sector. The second article describes how researchers created the fastest quantum computer bit by using lasers to trap the spin of a single electron in a quantum dot. The third article talks about research into allowing robots to predict where their leader is going based on cues, so they can follow the leader around corners.

2. Double play in Nigeria: ipNX will use WiMAX to carve itself a niche offering voice and broadband INFORMATION TECHNOLOGY RELATED NEWS 1

3. ISPs across the continent are being squeezed by the entry of the mobile companies into the Internet sector. There is double whammy hitting them: some mobile companies are buying their own ISPs whilst others are simply offering mobile broadband through EVDO and 3G. Nigeria’s ipNX’s has a strategy which mirrors the success of the CDMA 2000 fixed wireless product but it will use WiMAX to offer both “plug and play” voice and broadband. Russell Southwood spoke this week to ipNX’s Group Managing Director Ejovi Aror in Lagos.

5. ScienceDaily (Aug. 25, 2008) — The fastest quantum computer bit that exploits the main advantage of the qubit over the conventional bit has been demonstrated by researchers at University of Michigan, U.S. Naval Research Laboratory and the University of California at San Diego.

6. The scientists used lasers to create an initialized quantum state of this solid-state qubit at rates of about a gigahertz, or a billion times per second. They can also use lasers to achieve fundamental steps toward programming it. A conventional bit can be a 0 or a 1. A quantum bit, or qubit, can be both at the same time. Until now, scientists couldn't stabilize that duality. Physics professor Duncan Steel, doctoral student Xiaodong Xu and their colleagues used lasers to coherently, or stably, trap the spin of one electron confined in a single semiconductor quantum dot. A quantum dot is like a transistor in a conventional computer. The scientists trapped the spin in a dark state in which they can arbitrarily adjust the amount of 0 and 1 the qubit represents. They call this state "dark" because it does not absorb light. Therefore, light does not cause loss of coherence between the two states. In other words, the light does not destabilize the qubit. A paper on these findings will be published in Nature Physics and is available early in the online edition.

7. INFORMATION TECHNOLOGY RELATED NEWS 3 Robots Learn To Predict Where Their Leader Is Going, And Follow Along

8. ScienceDaily (Aug. 29, 2008) — Whether driving on the highway or walking down the street, we pick up on both deliberate signals and unconscious cues to predict what other people are going to do and act accordingly. But robots have trouble following each other around, for example, when a leader turns a corner and disappears from sight.

9. Researchers at UC Davis have come up with a control system that allows a robot to pick up on cues that the leader is about to turn, predict where it is going and follow it.
