med dev writes "An article at New Scientist discusses the latest in quantum computing - 1000 bits stored in the electron spins of a single polymer molecule. Add in a recent release of the how-to for the complete quantum computer, qubits that work, and it may not be much longer before Google is running on a server the size of a sugar cube."
So the scientists have succeeded in encoding a tiny black and white picture on a polymer molecule. Hooray! Another tiny step for science, but a giant leap for mankind. However, realitically, I don't think Google will be running on a sugar-cube sized memory bank any day now. The money to move that kind of infrastructure onto a quantum computer is unthinkable.
So, a wonderful step forward....but there are still many many steps left.

Just because you don't see the possibilities inherent in something does not mean that the thing has no value or is not relevant.
Besides, with the way things are moving, I can imagine the possibility of a computer that needs no clumsy interface cables, no removable media, and such... We're moving closer to being able to make systems that truly have no moving parts.
After all, there was a time when computers were built around the size and heat of vacuum tubes. Someday, probably not all that long, the interface mechanisms, storage devices and display systems we use today will be as quaint as a vacuum-tube driven computer programmed by hard-wiring it seems to us now.
so we can store information on a molecule, but how big was the machine that created the spins? And how long did it take to process the 1's and 0's on the molecule?
Sure, we could store information on molecules, but the speed and the size of the machines involved would put us back to working with punch cards...
What needs to be done simultaneously is to improve the method in which we induce and read the spin in molecules, or those sugar cube sized computers will just be expensive and slow RAM inside a computer the size of a room...
This article is about storage, not processing. And quantum bits of this type are pretty damn dense. Guess what--Google needs to store a lot of data. Yes, the experiment described isn't much more than an interesting proof-of-concept, but there is tremendous promise. "Google in a cube" is a bit of journalistic license, but I'll still be impressed when we're putting just the Google cache into a sugar cube.
