a set of magnetic nuclides inside a real molecule is very far from the abstract mathematical concept of a qubits register, especially considering the required but idealized spin-spin interactions ?! We are desperately trying to find real physical systems which would match our pre-conceived idea of a quantum computer rather than abstracting common features from reality the way we did in other cases (boolean, neural, fuzzy, genetic, ... computers and algorithms). We could be lucky, of course, but after so many decades and 100+ monographs it appears unlikely. Successful technologies usually flare up very fast and shine brightly within a few years after discovery (think about the glorious first decade of NMR).
