The working principles of the device are based on sequential tunneling of single electrons between the phosphorus atom and the source and drain leads of the transistor. The rapid development of computers, which created the present information society, has been mainly based on the reduction of the size of transistors. In the recently developed transistor, all the electric current passes through the same single atom. This allows researchers to study the effects arising in the extreme limit of the transistor size.Problems arising when the size of a transistor is shrunk towards the ultimate limit are due to the emergence of so-called quantum mechanical effects. On one hand, these phenomena are expected to challenge the usual transistor operation. On the other hand, they allow classically irrational behavior which can, in principle, be harnessed for conceptually more efficient computing, quantum computing.The driving force behind the measurements reported now is the idea to utilize the spin degree of freedom of an electron of the phosphorus donor as a quantum bit, a qubit."http://www.sciencedaily.com/releases/2009/12/091206085833.htmhttp://www.news.cornell.edu/releases/June02/McEuen.transistor.deb.html

This is a big leap into the advancement of quantum mechanics. In the subatomic level there are a whole different set of rules of physics compared to our normal world. We could speed up transfer rates of data with the new phosphorous transistor. If only we could get a quantum computer processor out in development we could make data analyzing much faster and access patterns of nature to predict outcomes to save life or make lives more efficient. A quantum computer can do a years worth of data building from the fastest computer know in one hour. Just think if we put that to analyzing traffic patterns or a broadband server.
