Single-Photon LED: Key To Uncrackable Encryption?

nut writes: "The BBC are carrying this story of new type of LED so precise that it can emit just one photon of light each time it is switched on. It has been developed by scientists from Toshiba Research Limited and the University of Cambridge. It is described in the journal Science, although I can find no mention of it on their website. One of the applications of this is supposedly uncrackable encryption, due to the law of indeterminacy. This application is described fully in 'The Code Book', by Simon Singh, although the method was only theoretical at the time the book was first published."

    If you had an entire array of these single-photon lights, couldn't it add an eerie glow to an object? Hopefully we can nanoscale these LED's and make things glow eerily.

    Job? I don't have time to get a job! Who will sit around and bitch about being broke and unemployed then?

    I *know* it's an LED, but the question is, can you run Linux on it?

    Sorry, this only gets 3/10 as a troll. I appreciate the attempt at humour but you contradict yourself all over the place, and are a bit *obvious* with some attempted analogies and factual inaccuracies. Plz make the satire a bit more subtle next time.

    Look forwards to next attempt,

    Phillip.

    I'm sorry, I must say that for once scientists have charged ahead and decided that stem cell research is for the benefit of all humanity, and should be applauded! After the fucked up things scientists have given us (the nuke, et al) it's good that something which acts at the fundamental, medical level - not just a new toy - is being taken seriously enough that those with the knowledge are willing to risk going to jail to bring it to us.



    "Ethical" ramifications are never hashed out. People just argue ad infinitum. How long, exactly, would you say they should wait? Until either everyone on earth shares the same religion or there is no religion anywhere? Until everyone is in exactly the same sociopolitical caste and there's no racism, so everyone agrees? Dream on. Stem cell research will do more to improve the lives of humans than anything prior. Just give it time to become available to everyone. Not developing it won't make anyone's life better. So why wait?
