U.S. Government Ponders Quantum Computer Regulation

If ironic or Kovacs-lent bonds are formed then the charm and strange quarks are irretrievably comingled making it impossible to determine the exact nature of the funniness of the related comment.

What?

[Basilides]

The combination of quantum computation and nanotechnology makes the mind boggle (as best it can at something it doesn't have the ability to comprehend).

We are in very scary territory the next few decades....

We can only "hope" that the same semi-benovelent attitudes prevail among those who possess this technology as those which prevailed among the controlling interests in the Manhattan Project.

If not...

[zeugma]

and data is governed by the uncertainty principle.

Ah, I see that you run Microsoft Windows. ;-)

Oh yeah. Nancy Pelosi's promised it'll be used only for Doom 12.

You beat me to it, Vermonter. I didn't know it was such common knowledge that silicon semiconductor technology was acquired from unwilling aliens.

How long do you think they will have to wait to reveal the quantum computational capabilities they also gleaned from the Roswell crash so as to not And wake it seem too suspicious?

Wait till they find out that OS X already runs on it.

Hmmm. It looks like we'll be seeing some very long keys being used by those who need/want privacy. Enough RAID 0s (interleaving) in RAID arrays will make that feasible, though.

...time to review a few things. I don't need such encryption, but others will want it.

All the cables are entangled and data is governed by the uncertainty principle.

And what do you use as a source of Brownian motion for your probablility drive?

Actually, for many applications, the one-time pad is actually quite practical. Consider that if all my communication with someone is via 115.2kbps link, a 40GB hard drive could hold enough 'pad' to encrypt about 2.5 years' worth of continuous transmissions. So, before my agent goes out into the field I fill up his hard drive with some carefully-generated random data and keep a copy for myself. To be sure, generation of 40GB of really good random data is not exactly trivial, but I believe there are some cryptographically-sound methods of "stretching" randomness (there are some risks entailed with this, and it's easy to go very badly wrong, but it's possible to arrange things so that inferring anything about a particular bit, even given infinite computing power, would require access to so many other bits that an adversary with such access would likely have access to the entire key anyway).

I'm already networked. I can't imagine being entangled. I guess every time a file is saved another file disappears.

"I've got a quantum computer now. All the cables are entangled and data is governed by the uncertainty principle."

So, you've got a messy desk and a computer running Windows. Welcome to the club.

;)

Who votes for these friggin morons?

Ah, advanced tea substitute....

Remingd me of the time we manufactured some advanced tobacco substitute and gave it to some poor test subject to review.... but that's a story for later..

During the 1990s, the U.S. government put strict controls on the export of technology, but has relaxed its stance somewhat due to the growing global economy.

I think the relaxation had more to do with Bill Clinton's campaign financing than with any Global Economy.

Consider that if all my communication with someone is via 115.2kbps link, a 40GB hard drive could hold enough 'pad' to encrypt about 2.5 years' worth of continuous transmissions.

40e9 / (115.2e3/8) / 86400 = 32.15 days ... and that's if CWO Walker doesn't handle your drive.

[HiTech RedNeck]

This would necessarily be one of the most closely guarded secrets in the world. Whoever has access to QC can immediately break almost any cryptographic scheme (except for one-time pads and quantum cryptography). Of course the government would go to great lengths to protect this monopoly.

This would also blow the security off of internet commerce overnight. If the science is near at hand, not just governments are going to be questing for it.

[familyop]

Thanks. I'm not familiar with the one-time pad or that terminology, but randomizing whole drives before encryption is a good idea--much better than zeroing them (leaves usable data sections too visible).

Is one-time pad a marketing name or generic method?

And BTW, for all, the following might be of relevance to the posted article.

Ah, I found it (info on one-time pad).

http://en.wikipedia.org/wiki/One-time_pad

I'll run it through fellow BSD eggheads and check it out. ...haven't focused on crypto stuff but a little (played with encrypting swap space with cgd and the like).

Does this mean that we can now fashion "tin-foil" hats and wear them without anyone being the wiser?
