German Scientists Create 5 qubit Quantum Register

Posted by timothy on Tuesday October 12, 2004 @12:28AM from the sehr-klein dept.

CMan0 writes "In the University of Bonn, a team of scientists has built a 5 qubit register, using cesium atoms trapped by a laser-beam grid, The Register reports. They've been able to install an empty 5 bit register(i.e. all bits 0), change two of them to 1, and later read those 1s back. The next goal is to create an interaction between 2 bits. The full scientific article can be found here in PDF format."

Should the first quantum OS be M$ or Linux? :) I like to watch people argue about OS's. Makes me smile.

  Except that you can't control which operating system comes up: That will be completely random. If you are unlucky, you'll get the desired operating system only after a lot of boot cycles.

  But since all possible boot cycles happen simultaneously, this shouldn't be a problem.

  Actually, there was uncertainty.
  
  Well, there was Fear, Uncertainty and Doubt.
  
  Uncertainty was finally implemented int he basic laws of matter, while Fear was reserved to animals (including humans) and Doubt was reserved for the humans alone.

What they didn't know, was that (like all good sci-fi comics prior to the graphic novels of the late 80's) there was only one way to unlock the door of the secret super evil overlords of darkness... and that was a 6 qubit register!

Caesium atoms are quite cheap, especially when you need several of them. They are just looking forward to a future scenario where they might need to invest in 10 or even 15 atoms.

I got 5 caesium atoms free from Ron Popeil when I ordered my Showtime Rotisserie! They came in a seperate package from the steak knives. That's probably where these scientists got their's. That's why they used five atoms I suspect. To bad they didn't have money to buy the second Rotisserie and get a ten atom computer. I couldn't find a laser standing wave generator on Ron's site though. hmmmm.
