Quantum Computers

This article at Scientific American discusses recent developments towards the goal of 'infinite computing,' and research is showing that scalibility may not be far away, and thus scalable qbits."

I remember seeing something about atom trapping. I was able to find a tone down version of the Science magazine article here: www.academicpress.com/inscight/06022000/graphb.htm

Schmiedmayer, who's mentioned in the parent story, is also in this story from mid-last year.

A recent slashdot article that I submitted also concerns the aspect of using silicon buckyballs as cages for qubits.

The crux of the matter still remains unsolved in this SciAm article, and I have yet to see any explanation on how to solve it in any of the scientific journals that I read: that is, we don't use pure quantum states to preserve the very fickle quantum condition. When we can do that - there have already been enough postulation on what a qubit can consist of - then we can seriously consider quantum computing in the future.
