Roland Piquepaille writes “Quantum computing is usually associated with extremely low temperatures. Physicists at Harvard University have shown that diamonds can be used to create stable quantum computing building blocks at room temperature. A nitrogen vacancy in diamond could lead to quantum registers able to store or retrieve data. ‘”The problem is, what makes single nuclear spin so stable – its weak interaction with its surroundings – also prevents us from directly manipulating it,” Lukin says. “How do you control something that can’t interact with anything?” You do it gingerly and indirectly, the Harvard physicists report in Science. They found that nuclear spins associated with single atoms of carbon-13 – which make up some 1.1 percent of natural diamond – can be manipulated via a nearby single electron whose own spin can be controlled with optical and microwave radiation.’”

Turn on your monitor and boot up your computer, because class is in session. Many college students now raised on the Internet and mobile devices will not be limited to sitting in traditional “brick-and-mortar” classrooms as schools look to the latest offerings in virtual technology and Internet broadcasting to update education. New developments have made it easier and cheaper for professors to expand their lectures in directions beyond posting electronic message boards and broadcasting archived lectures.

An anonymous reader writes “The New Zealand Ministry of Education has declined to renew a licensing deal for MS Office on 25,000 Macintosh computers in the country’s schools. The Education Minister has suggested that schools use the free alternative NeoOffice. The article quotes a school principal who pointed out that the NeoOffice website warns users to expect problems and bugs: ‘That’s not the sort of software we should be expecting kids in New Zealand to be using.’” Schools are free to buy their own copies of Office. A blog on the New Zealand Herald site argues that the Ministry should have paid Microsoft this time, but not renewed the deal and instead developed a transition plan to open source.

An Illinois pilot technology program that will provide about 1,150 Apple MacBook computers to Springfield’s public schools certainly seems like a great idea. Or does it? Much has been written about the digital divide — wealthier kids tend to have access to the wonders of the World Wide Web while poorer kids are often left in the digital dust. The concept behind providing top-notch laptop computers to students is in part to overcome that divide. The theory is that the laptop computers could be a huge academic boon to students.

h2g2bob writes “Ben Goldacre reports that the BBC Panorama team, while scaremongering over the dangers of Wi-fi, were told to leave the school because even the kids could see it was dumb: ‘When the children saw Alasdair’s Powerwatch website, and the excellent picture of the insulating mesh beekeeper hat that he sells (£27) to protect your head from excess microwave exposure, they were astonished and outraged. Panorama were calmly expelled from the school.’ Should we be pleased that the kids can out-think TV producers?”
