The up-or-down spin of nuclei offers the two-bit logic system that a computer needs. What makes a quantum computer special, however, is quantum parallelism. In the strange world of quantum mechanics, the spin of a nucleus can be in both states, representing both bits, at the same time. That property should permit a quantum computer to perform calculations on incredibly large numbers of bits at once. And Neil Gershenfeld of the Massachusetts Institute of Technology and Isaac Chuang of the University of California, Santa Barbara, and a second team, Tim Havel and Amr Fahmy of Harvard Medical School and David Cory of MIT, have found that it's easier to achieve this parallelism by using NMR in an ordinary liquid than in the exotic systems researchers have tried so far.<p> Cory, Fahmy, and Havel have actually built quantum circuits using a standard NMR spectrometer, while Gershenfeld and Chuang are gearing up experiments and hope to demonstrate quantum circuits and maybe even a simple computation by next summer. What can be done now can be done with easily available and affordable equipment--"off-the-shelf coffee cups, off-the -shelf liquids, off-the-shelf magnets, etc.," says MIT computer scientist Seth Lloyd.<p> "This NMR scheme is pretty slick stuff, but in the long run, they're going to have to find a particularly special molecule or state that allows them to extend it to large numbers," says Chris Monroe of the National Institute of Standards and Technology.<p> Indeed, the researchers note that fundamental obstacles may prevent the scheme from ever producing a practical computer. But "from the point of view of verifying the basic ideas and doing interesting physics," says Lloyd, a pioneer theorist in quantum computing, "it's fantastic."

The problem here is that the terms "infinity" and "number" are used to refer to many different things in mathematics. We use "infinity" as a term for transfinite Cardinals and Ordinals, but also use it when describing convergence on the reals, to indicate that a sequence increases without bound. We use it in calculus to describe the limits of integration over all real numbers, a set which does not include any infinite numbers at all. Similar we use the term "number" to refer to Cardinals, Ordinals, Reals, Integers, Complex, Quaternians, or whatever, hoping that what we mean by it will be clear from the context. With respect to the Real numbers, infinity is not a number, but simply a way of saying something increases without bound or that we wish to include all the positive or negative reals when performing some mathematical operation. With regard to Ordinals and Cardinals, not only is infinity a number, but there are an uncountable number of different infinities, which cannot be placed in 1-1 correspondence with each other. -- Mike Duvos $ PGP 2.6 Public Key available $ mpd(a)netcom.com $ via Finger. $

Disseminating public-key crypto source code
by Jon Orwant 17 Dec '03

17 Dec '03

I've written a few Perl routines for public-key cryptography. I'd like to freely disseminate the source code (starting with ElGamal) to as many people as I can, It's my understanding that there are two orthogonal restrictions: 1) ITAResque: I can't give code to non-U.S. citizens. 2) PKPesque: Using public-key crypto is an infringement, although disseminating/possessing the source code is not. While I'm sure these are oversimplifications, it would seem that I can release my source code over the Internet provided I install a simple verification mechanism (cf. MIT's PGP distribution) to ensure that only people claiming to be U.S. citizens have access privileges. Am I correct? If so, why aren't more people doing this?

By your > acidic comments, are you trying to tell us something? Homosexual activists have accused many prominent people, like Hoover and da Vinci, of sharing their sexual perversions. I have seen no evidence that Hoover was a pervert other than a claim by one woman, a proven liar, that she was present at an orgy where Hoover wore a woman's dress and engaged in sex with men. Several other people who she claimed were present at the orgy called her a liar. She's dead, or she would have probably been supporting Geekmore and EFF today. You may recall that the moderator cocksucker Sandfart invited me to a "cypher punks" meating in San Francisco, and if I had accepted, would have told many lies about my participation in their homosexual orgies. --- Dr.Dimitri Vulis KOTM Brighton Beach Boardwalk BBS, Forest Hills, N.Y.: +1-718-261-2013, 14.4Kbps
