KentuckyFC writes “Quantum cryptography uses the quantum properties of photons to guarantee perfect secrecy. But one of its lesser known limitations is that it only works if Alice and Bob are perfectly aligned so that they can carry out well-defined polarization measurements on the photons as they arrive. Physicists say that Alice and Bob must share the same reference frame. That’s OK if Alice and Bob are in their own ground-based labs, but it’s a problem in many other applications, such as ground-to-satellite communications or even in chip-to-chip communications, because it’s hard to keep chips still over distances of the order of the wavelength of light. Now a group of UK physicists have developed a way of doing quantum cryptography without sharing a reference frame. The trick is to use entangled triplets of photons, so-called qutrits, rather than entangled pairs. This solves the problem by embedding it in an extra abstract dimension, which is independent of space. So, as long as both Alice and Bob know the way in which all these abstract dimensions are related, the third provides a reference against which measurements of the other two can be made. That allows Alice and Bob to make any measurements they need without having to agree ahead of time on a frame of reference. That could be an important advance enabling the widespread use of quantum cryptography.”

VJ42 writes “With the 2010 UK general election fast approaching, The Pirate party of the United Kingdom will be fielding elections for the first time. The Digital economy bill and ACTA are hot topics for UK geeks, and the Pirate party is looking to pick up some votes. Their leader Andrew Robinson has agreed to answer your questions. Normal Slashdot interview rules apply.”

Grumbleduke writes “During today’s debate in the UK’s House of Lords on the much-criticized Digital Economy Bill the unpopular Clause 17 (that would have allowed the government to alter copyright law much more easily than it currently can) was voted out in favor of a DMCA-style take-down system for websites and ISPs. The new amendment known as 120A sets up a system whereby a copyright owner could force an ISP to block certain websites who allegedly host or link to infringing material or face being taken before the High Court and made to pay the copyright owner’s legal fees. This amendment was tabled by the Liberal Democrat party who had so far been seen as the defenders of the internet and with the Conservative party supporting them. The UK’s Pirate Party and Open Rights Group have both strongly criticized this new amendment.”

Hugh Pickens writes “The NY Times reports that the BBC has yielded to critics of its aggressive expansion, and is planning to make sweeping cuts in spending on its Web site and other digital operations. Members of the Conservative Party, which is expected to make electoral gains at the expense of the governing Labor Party, have called for the BBC to be reined in and last year James Murdoch criticized the BBC for providing ‘free news’ on the internet, making it ‘incredibly hard for private news organizations to ask people to pay for their news.’ Mark Thompson, director-general of the BBC, said ‘After years of expansion of our services in the UK, we are proposing some reductions.’ The BBC is proposing a 25 percent reduction in its spending on the Web, as well as the closure of several digital radio stations and a reduction in outlays on US television shows. The Broadcasting Entertainment Cinematograph and Theatre Union, which represents thousands of workers at the BBC, says that instead of appeasing critics, the proposed cuts could backfire. ‘The BBC will not secure the politicians’ favor with these proposals and nor will the corporation appease the commercial sector, which will see what the BBC is prepared to sacrifice and will pile on the pressure for more cuts,’ says Gerry Morrissey, general secretary of the union.”

redalien writes “In 2008 I invited two policemen into my home and voluntarily gave them a DNA and fingerprint sample to help with a murder investigation, as they’d promised it would only be used for that investigation. I was never under any suspicion and could just as easily have said no. Almost a year after the investigation closed they have now confirmed that they’ve retained my samples and at my request have begun an investigation to see if there are sufficient ‘exceptional circumstances’ to remove them. I’m not the only one who was told samples would be removed, so if you’ve had such a promise from the police I recommend contacting their data protection registrar immediately.”

suraj.sun writes with this excerpt from ZDNet about another troubling aspect of the UK’s much-maligned Digital Economy Bill:
“The government will not exempt universities, libraries and small businesses providing open Wi-Fi services from its Digital Economy Bill copyright crackdown, according to official advice released earlier this week. This would leave many organizations open to the same penalties for copyright infringement as individual subscribers, potentially including disconnection from the internet, leading legal experts to say it will become impossible for small businesses and the like to offer Wi-Fi access. ‘This is going to be a very unfortunate measure for small businesses, particularly in a recession, many of whom are using open free Wi-Fi very effectively as a way to get the punters in. Even if they password protect, they then have two options — to pay someone like The Cloud to manage it for them, or take responsibility themselves for becoming an ISP effectively, and keep records for everyone they assign connections to, which is an impossible burden for a small cafe,’ said Lilian Edwards, professor of internet law at Sheffield University.”
Relatedly, an anonymous reader passes along a post which breaks down the question of whether using unprotected Wi-Fi is stealing.

superglaze writes “The European Commission is ‘not supporting and will not accept‘ any attempt to have ACTA (the Anti-Counterfeiting Trade Agreement) force countries to disconnect people for downloading copyrighted material, a spokesman for the new EU trade commissioner has said. All the signs are that the new commission, which took office earlier this month, intends to take a hard-line stance against US proposals for a filesharing-related disconnection system. ‘Three strikes’ is allowed in EU countries, but not mandated by the European government itself, and it looks like the new administration wants to keep it that way. From trade commission spokesman John Clancy, quoted in ZDNet UK’s article: ‘[Ac ta] has never been about pursuing infringements by an individual who has a couple of pirated songs on their music player. For several years, the debate has been about what is “commercial scale” [piracy]. EU legislation has left it to each country to define what a commercial scale is and this flexibility should be kept in ACTA.’”

registerShift writes “Virgin said it will roll out 100 megabit-per-second broadband connections to homes in the UK. The company said users will experience speeds ‘very close’ to what’s advertised as it plans to deploy cable instead of ADSL used by competitors. “There is nothing we can’t do with our fibre optic cable network, and the upcoming launch of our flagship 100mbps service will give our customers the ultimate broadband experience,” Virgin Media’s chief executive officer, Neil Berkett, said. This is just days after the FCC announced aims of 100Mbps by 2020, and companies panned it as unrealistic.”

Squiff writes “The British Library warns us that ‘The UK’s online heritage could be lost forever if the government does not grant a “right to archive”‘ in the UK. Never mind the Wayback Machine, The British Library declares that ‘the average life expectancy of a website was just 44 to 75 days, and suggested that at least 10% of all UK websites were either lost or replaced by new material every six months,’ with the material within them being amongst the most revealing regarding the state of contemporary culture.”

superapecommando writes in with a neutral introduction to net neutrality from ComputerWorld UK. While it doesn’t go into a lot of technical depth, it’s rare to see anything written on the subject that isn’t rabid on one side or the other. “Google’s recently announced plan to set up trial fiber-optic networks in the US with ultra-high-speed Internet connections puts the long running national debate over Net Neutrality back into high gear. A hot topic of discussion and debate in government and telecom circles since at least 2003, Net Neutrality, actually involves a broad array of topics, technologies and players. Here’s a primer for those looking to get up to speed fast.”
