(PhysOrg.com) -- "One of the most exciting things about this is that it gives us nice, clean control over the interaction between light and matter," William Kelly tells PhysOrg.com. "Our technique has the potential to give ...
A quantum computer could provide an enormous improvement in the processing speed of existing computers. However, as yet they only exist in the laboratory in the form of small prototypes with a capacity of a few bits. They ...

In classical physics there are no uncertainties - the properties of matter on an atomic level are deterministic, that is to say predetermined. The theories of quantum mechanics, however, only say something about how likely ...
