Short little blurb on MSNBC web push
(I do not know how long it will remain valid,
sent on 5/19)
Here are some links
(this was a hyperlink in the article "wired together"
that they had the wrong address)
Los Alamos Cryptography blurb
(this one has to be a joke, they have a link to image's
of Alice's and Bob's computers, kind of a silly personal page)
Essentially the system uses a scheme called entanglement
in which two ions have their quantum states
linked at a distace (I think they use laser light over fiber
Still more hype that reality but they are getting on
the next step of generating these quantum bits (qnbit) to store
information and state. Then supposedly, they could form a
prime factoring machine using these qnbits. A quantum code
cracker machine would essentially be set up, the act of reading
its state solves the problem.
A new analogy I thought up is trying to find the longest non looping path
in a spider web. Given a starting point on a wall where a web strand
is connected, the web forms a maze pattern ending in other strands
conected to another wall (the end points).
If you could pull the web off the wall and label all end points and
each strand, the longest distance between two points is found by holding
each start/end point and carefully pulling them apart, if you
break a strand but leave another path intact, you keep pulling. The moment
you cannot pull any further without seperating the start and end point,
that is the longest path. Of course the web was destroyed in doing the
measurement. If a quantum computer is doable, I think it would operate
in a similar way. The problem is formed by setting up the states of the
computer's particles. The particles would fall into any of the
solution states according to the rules of the particle logic.
In reading the state of the particles, you freeze the system into a
single solution state.
