Analysis Spock?
Right now all chips are limited by the speed of electrons.
This breakthrough means the speed of light would be limit.
I think in principle the ideas are of the same kind that one finds in solid state theory of cavities and defects and so on, but here they are striving to get control over things so they can build lattices of interactions on a quantum level.
To what end, I can't really say, because to me the whole idea of gaining control over the quantum realm is fundamentally hopeless, since it is axiomatic in Quantum Theory itself that this will not happen, as expressed by Quantum Uncertainty.
But what do I know?
