Scientific American on Quantum Encryption
prostoalex writes "Scientific American claims that advances in commercially available quantum encryption might obsolete the existing factorization-based solutions: "The National Security Agency or one of the Federal Reserve banks can now buy a quantum-cryptographic system from two small companies - and more products are on the way. This new method of encryption represents the first major commercial implementation for what has become known as quantum information science, which blends quantum mechanics and information theory. The ultimate technology to emerge from the field may be a quantum computer so powerful that the only way to protect against its prodigious code-breaking capability may be to deploy quantum-cryptographic techniques.""
Someone needs to write a Encryption routine that uses the source text as the key. THAT will really show 'em!

As far as I can tell, no cats were harmed in the making of these quantum cryptographic devices, although if you look inside the box, the act of looking at the cat inside may (or may not) kill it

Quantum computing doesn't make threats.
It makes promises.
I'm not just gunna break yo' face, i'm going to quantum break yo' face, foo'!
*I'm not just gunna break yo' face, i'm going to quantum break yo' face, foo'!*
so you gonna break his face and slam a cardboard box over his head? "no officer, his face is not smashed. however, if you take the box off it might cause it to be smashed or not"

so long bits, hello tits.
Trinary digITs here we come!
lol: You see no door there!
And then I'll quantum-borrow the cop's glock and quantum-unload a clip into the box.
I quantum-love science!

Oh my God, you're right. We will stop our work immediately, I can't believe we didn't think of this before.

"...a quantum computer so powerful that the only way to protect against its prodigious code-breaking capability may be to deploy quantum-cryptographic techniques."
scary stuff....however, a simpsons quote comes to mind:
Alien 1: It seems the earthlings won.
Alien 2: Did they? That board with a nail in it may have defeated us. But the humans won't stop there. They'll make bigger boards and bigger nails, and soon, they will make a board with a nail so big, it will destroy them all!
[both aliens laugh evilly, for quite some time]
This sig contains repetition and redundancy.
VERY rough explanation.
Encryption algorithms rely on the fact that some problems need an exponential number of 'calculations' to be solved. If b is the number of bits in a key, breaking the encryption needs 2^b steps.
On the other hand in traditional computers, if you have p processors and each can perform n calculations per time unit, then you can perform p.n calculation in total. Increasing p or n gives only a *linear* improvement in performance. This is not enough to match 2^b if b is big enough.
On the other hand with q Qbits you can perform 2^q calculations simultaneously (nature's miracle). Take b Qbits and you're done (I said rough explanation, remember). The only problem is that its VERY dificult to tie QBits together.
So the big question is: Why does Alice have so many secrets? Why does she feel compelled to tell Bob everything? And what is up with Eve, always budding in?
Personally I think there's something going on between Eve and Bob, that they're not telling us. But damned if I can't break their code.
yo.
Does NSA secretly have a quantum computer that can do that? I'd say its extremely unlikely...
Actually, they do! And the infinite improbability field that it generated is the true reason behind the November election results.
So what you're saying, basically, is that you can't tap into quantum encryption without destroying the communication/ randomizing the bits in the process and that the nsa isn't THAT far ahead of current public research and that , oh hang on
Mongrel News all the news that fits and froths
Before you'll know it the will be another hot-or-not spinoff called "is my cat dead-or-not" and it will be a bunch of blank pictures.
I don't get it.
I can't see PETA, or event myself for that matter, going along with a quantum encryption system when every time you unencrypt and open the box/vault/computer/etc. there is a 50/50 chance of killing a cat.
