@pixies, 'never' is a strong word and i have learned during my studies to not say never as in Science impossible is just a breakthrough result away!

I belive that people typically underesitmate efforts required in materials science, this is not software or another chip design in well established CMOS process. It might easily take 20 years to make high volume, manufacturable spin based device. Severeal examples of new material developments that took 30-40 years do exist...Kris

I have the same doubt. Are there any factors which could affect the spin of the nuclei and in-turn loose your data ?

What I see is the demise of the current semiconductor memory technologies by 2020!

It seems that this device can never operate at room temperature. I do not see an application in the foreseeable future. But it is really cool physics.

After sucessfully developing a practical quantum entanglement technology, I wonder what will happen when like material is placed near the device. Will alpha/beta/gamma radiation affect atomic spin? Will radiation affect the ability to refresh data over time? Plastic or epoxy packaging can have a small radioactive component. These and other questions must be answered to achieve a working, reliable product.

quantum computers are still decades away, in my opinion, as simultaneous manipulation of group of atoms/electrons/photons is required. this article has good news about the long decay time of the information, which is very crucial for any kind of practical use.

NIST has been demonstrating how to store quantum information on atoms and last week Duke University and the University of Wisconsin showed how lasers could be focused with MEMS micro-mirrors to read and write them in their gaseous state: http://bit.ly/NextGenLog-h8ti However, this University of Utah researcher takes the next step--holding out the promise of being able to store quantum information on solid-state atoms that can be read and written electrically, opening the door to quantum computers fabricated on chips just like conventional computers.
