Practical Quantum Cryptography

Posted by timothy on from the next-year-it'll-be-in-wristwatches dept.

Alien54 writes: "Saw this on Eureka Alert: A commercially available system for quantum key distribution and cryptography has been released by a spin-off company from the University of Geneva. The system has been tested over distances up to 70km (from Geneva to Lausanne) through standard optical fiber cables and connects to PCs via USB ports. Transmission rates of about 60 bits per seconds were achieved, sufficient for key distribution. You can see the original abstract here, which also has a link for download of the paper in PDF, Postscript, and other formats."

    Proof that you don't need to pay 20'000$ a year to study in a University doing advanced research.

    I went to University of Geneva, I paid 300$ a semester, poor students(decided by their income) pay 40$ a semester, and this is valid for every department.

    Now, if only US Universities could learn from them...

    Oh, before the argument comes: no, in Switzerland we don't pay much more taxes than in USA, we pay a bit more, but not that much.

      "higher capital gains tax

      Which would be perfectly reasonable. Those have a large personal wealth must also make larger contributions back to the society. Unless they wish to renounce their membership in the society, which is, of course, completely permissible. Too bad you cannot do business with the members of the said society anymore then. "

      It is NOT "perfectly reasonable." It is barbaric.

      Sorry, Comrade, 20% of $1,000,000 is a larger amount than 20% of $50,000. If the tax tables were uniform then the "rich" would still pay more money. Making someone pay 40% of their income in taxes just because they make more than you is so backward that it is beyond comprehension.

      As far as Capital Gaines Taxes go, they are mearly a tax on investments (realestate included) IN ADDITION TO YOUR INCOME TAX. It is also dual taxation, in some cases (yes this is a qualifier and part of the same sentence), dual taxation when applied to stock dividends and sales of stock. Hell, it is dual taxation when you sell a house that qualifies, since you paid tax on the money to buy the home with and all of the repairs made to the house BEFORE spending the money to make the purchases (house, labor, materials, etc)!

      Not sure why you lefties want to punish people for being financially successful, hell, you want to punish people for being self sufficient too, but it is just stupid so knock it off. Some of us do not want to be wards of the state.

      If YOU think the government deserves more of everybody's money there is NOTHING stoping YOU from sending in your whole paycheck.

      Still pay more money? [laugh] "Only the little people pay taxes."

      Because he is parroting leftist "ideas" using the interesting vehicle of quoting from a convicted, wealthy, tax evader. From one example he supports his whole "theory."

      Gives some insight to what /.ers percieve as truth, since everything with a valid point was modded down and his crap keeps a 2.

      Thank you for the real stats, but I am sure you will be attacked for not being specific enough, or one of the AC chickens will be pouncing on your syntax.
