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.

      "....Switzerland's top federal income tax rate is 11.5 percent. (According to the international accounting firm Ernst & Young, "No average tax can be calculated because of the multilayered tax system. Taxes are calculated based on specific figures for specific cantons and municipalities. The maximum overall rate of federal income tax is 11.5%.") The top marginal corporate tax rate is 32 percent......"

      "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.

      An offtopic troll, but I'll still bite:

      The system where the percentage increases the more money you make is based on the idea, that the more money you get, the more you can contribute. There's a certain amount of money the goverment has to make, one way or another. So you could put universal 30% or 20% for poor, that goes up with more income. Hence you 'take from the rich and give to the poor' in a way. The rich can afford it, the poor can't.

      Ahh, actually "we" understand this just fine and YOU do not.

      You seem to deny that $20,0000 is a bit more than $10,000. Double as a matter of fact. The person making more money IS contributing more, with a uniform percentage tax rate.

      You have a problem with someone that makes double than another "only" paying double, you need to soak them for some compleatly irrational reason. You have stated it, you want to redistribute income. Pretty irrational by any measure.

      See, to some of us there is a difference between a "contribution" being voluntary and a "contribution" being compusory. We would like to see everybody's COMPULSORY contribution be the same percentage, thus (yes, I know you are having trouble with this) the people that make more money DO make COMPULSORY contributions in greater amounts than those that make less money.

      Some of us would like to contribute more to much more worthy causes than say, spiking national parks with Lynx hair, as agents of the Department of the Interior did not too long ago, but people like YOU think that we are just not bright enough to make our own decisions with our own money. You know, since we think that our retired parents could use some direct help from US instead of some BS federal program, or our children could benefit from a private school better than the cesspool the government created and labelled a school. Things like that. But I digress...

      You also indicate that the only "contributions to society" are made through taxation then doled out by the government. Sorry Big Brother, there is much more to society than that. Sorry, but if I wish to contribute in ways that just don't fit your theft model, too bad.

      Your messed up "logic" falls apart from the start and never recovers. If YOU want to send every nickle to the government go right ahead. Leave my nickles alone thank you.

      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.
